It is an important selection reference, but it does<br>\n  not guarantee the performance of every completed installation.\n<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\n  Drilled openings, cable glands, unused cable-entry holes, mounting screws and cover<br>\n  installation can all affect the protection of the final assembly. Buyers should<br>\n  therefore confirm the applicable rating for the exact model and configuration being<br>\n  ordered.\n<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">IP65 Enclosures<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">\n  IP65 enclosures may be considered for installations requiring protection against dust<br>\n  and water jets, subject to the applicable product specification and installation<br>\n  conditions.\n<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\n  For systems containing modular circuit breakers or other DIN-rail components, an<br>\n  <a href=\"https:\/\/bowo-electric.com\/fr\/ip65-waterproof-electrical-distribution-box-for-din-rail-circuit-breaker-protection\/\"><br>\n    IP65 waterproof electrical distribution box<br>\n  <\/a><br>\n  with a transparent cover can support visual inspection without opening the main<br>\n  enclosure door.\n<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">IP66 Enclosures<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">\n  IP66 models are generally evaluated for more exposed locations or installations<br>\n  subject to stronger water jets. They may be used around outdoor equipment, distributed<br>\n  electrical connections and renewable-energy systems when the selected model and<br>\n  installation meet the project requirements.\n<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\n  When technicians require repeated access, an<br>\n  <a href=\"https:\/\/bowo-electric.com\/fr\/industrial-ip66-hinged-waterproof-junction-box-with-metal-latches-for-outdoor-electrical-protection\/\"><br>\n    IP66 hinged waterproof junction box with metal latches<br>\n  <\/a><br>\n  can provide easier access than a cover secured by multiple individual screws.\n<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">IP67 Enclosures<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">\n  IP67 describes dust protection and resistance to temporary immersion under specified<br>\n  test conditions. It should not automatically be interpreted as approval for continuous<br>\n  underwater use.\n<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\n  Distributed cable and terminal connections can consider an<br>\n  <a href=\"https:\/\/bowo-electric.com\/fr\/ip67-outdoor-waterproof-junction-box-for-electrical-cable-enclosure\/\"><br>\n    IP67 outdoor waterproof junction box<br>\n  <\/a><br>\n  when the model, cable glands, entry positions and site conditions are suitable.\n<\/p>\n\n\n\n<div class=\"article-note\">\n<p>\n    <strong>Important:<\/strong> The enclosure IP rating does not replace the electrical<br>\n    system design, component protection or installation requirements defined by the<br>\n    project engineer and applicable local standards.\n  <\/p>\n<\/div>\n\n\n\n<h2 class=\"wp-block-heading\">Select the Enclosure Around the Internal Components<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">\n  Choosing an enclosure only by its external dimensions is a common procurement mistake.<br>\n  Internal screw columns, mounting ribs, hinges, gaskets and cover structures reduce the<br>\n  usable installation space.\n<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The internal layout should allow sufficient room for:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>DIN rails and modular protection devices<\/li>\n\n\n\n<li>DC breakers, isolators or fuse holders<\/li>\n\n\n\n<li>Terminal blocks and grounding terminals<\/li>\n\n\n\n<li>Monitoring or communication modules<\/li>\n\n\n\n<li>Cable bending radius<\/li>\n\n\n\n<li>Safe separation between applicable circuits<\/li>\n\n\n\n<li>Installation tools and maintenance access<\/li>\n\n\n\n<li>Heat dissipation and component clearance<\/li>\n\n\n\n<li>Future wiring or component expansion<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">\n  For selected DC distribution applications, the<br>\n  <a href=\"https:\/\/bowo-electric.com\/fr\/htc-series-ip65-side-open-dc-distribution-box\/\"><br>\n    HTC Series IP65 side-open DC distribution box<br>\n  <\/a><br>\n  includes a transparent inspection area, internal guide rail and side cable-entry<br>\n  arrangement. The final suitability must still be confirmed according to the installed<br>\n  components and project conditions.\n<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Plan Cable Entries Before Ordering<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">\n  Cable-entry design is one of the most important parts of a waterproof electrical<br>\n  enclosure. A well-manufactured enclosure can lose its environmental protection when<br>\n  entry holes are incorrectly sized, positioned too close together or fitted with<br>\n  unsuitable glands.\n<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A complete cable-entry drawing should identify:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The number of incoming and outgoing cables<\/li>\n\n\n\n<li>The outside diameter of every cable<\/li>\n\n\n\n<li>The required gland or connector thread<\/li>\n\n\n\n<li>The entry surface and installation direction<\/li>\n\n\n\n<li>The center position of each opening<\/li>\n\n\n\n<li>The distance between adjacent openings<\/li>\n\n\n\n<li>Unused openings that require sealing plugs<\/li>\n\n\n\n<li>Required strain relief or conduit connections<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">\n  Bottom-facing cable entries are commonly considered for exposed outdoor installations<br>\n  because they reduce direct exposure to falling rain. However, the correct position<br>\n  depends on the cable route, mounting surface and equipment layout.\n<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\n  Buyers should send a dimensioned drawing whenever CNC machining is required. For an<br>\n  overview of machining, logo, color and structural options, see the guide to<br>\n  <a href=\"https:\/\/bowo-electric.com\/fr\/how-to-customize-waterproof-junction-boxes-for-oem-projects\/\"><br>\n    customizing waterproof junction boxes for OEM projects<br>\n  <\/a>.\n<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Choose Materials According to the Environment<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">\n  Material selection affects impact resistance, dimensional stability, appearance,<br>\n  outdoor durability and production cost. ABS and polycarbonate are common materials<br>\n  for plastic electrical enclosures, but they should not be treated as interchangeable<br>\n  in every environment.\n<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">ABS Enclosures<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">\n  ABS can provide a practical balance of mechanical performance, electrical insulation<br>\n  and manufacturing efficiency for many general industrial and selected outdoor<br>\n  applications. Long-term sunlight, chemical exposure and temperature requirements<br>\n  should be confirmed for the specific material grade.\n<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Polycarbonate Covers and Components<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">\n  Transparent polycarbonate covers are useful when circuit breakers, indicators or<br>\n  internal equipment need to be checked without opening the enclosure. Material<br>\n  suitability for ultraviolet exposure and impact requirements should be confirmed<br>\n  for the selected product.\n<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\n  Some projects use an ABS body with a transparent PC cover. This configuration can<br>\n  combine an opaque enclosure base with convenient internal visibility, but it does<br>\n  not remove the need to verify the complete product specification.\n<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Consider Heat, Condensation and Pressure Changes<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">\n  Solar and energy storage equipment may experience significant differences between<br>\n  daytime and nighttime temperatures. Heat generated by internal electrical components<br>\n  can also raise the temperature inside the enclosure.\n<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">During enclosure evaluation, project engineers should consider:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Heat generated by the installed components<\/li>\n\n\n\n<li>Expected internal and external temperature range<\/li>\n\n\n\n<li>Required clearance around heat-producing devices<\/li>\n\n\n\n<li>Possibility of condensation during temperature changes<\/li>\n\n\n\n<li>Whether approved ventilation or pressure-equalization components are required<\/li>\n\n\n\n<li>Whether ventilation changes the required ingress protection<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">\n  Ventilation holes should not be added without evaluating their effect on the enclosure<br>\n  protection. Any membrane vent, filter or pressure-equalization device must be selected<br>\n  as part of the complete enclosure system.\n<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Match the Cover Design to Maintenance Frequency<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">\n  The best cover structure depends on how frequently the enclosure must be opened.\n<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Screw-Fixed Covers<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">\n  Screw-fixed covers are suitable for connection points that are rarely opened.<br>\n  Tightening the cover screws evenly helps maintain consistent gasket compression.\n<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Hinged Covers<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">\n  Hinged covers are useful for equipment requiring periodic inspection or wiring<br>\n  changes. The cover remains attached to the body, reducing the risk of a separate<br>\n  lid being dropped or misplaced during maintenance.\n<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Transparent Covers<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">\n  Transparent covers allow technicians to inspect breaker positions, indicators and<br>\n  visible internal conditions without opening the enclosure unnecessarily. They are<br>\n  especially useful for distributed installations where routine inspection time is<br>\n  important.\n<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What Documentation Should a Project Buyer Request?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">\n  Procurement teams should not assume that every certificate shown by a manufacturer<br>\n  applies to every enclosure model. Documentation is normally model-specific and may<br>\n  depend on the material, size and product configuration.\n<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Before approving an order, request the applicable:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Product specification and dimensional drawing<\/li>\n\n\n\n<li>Material information<\/li>\n\n\n\n<li>IP or IK test information where applicable<\/li>\n\n\n\n<li>CE or RoHS documentation where applicable<\/li>\n\n\n\n<li>Installation instructions<\/li>\n\n\n\n<li>Cable-entry machining drawing<\/li>\n\n\n\n<li>Sample approval record<\/li>\n\n\n\n<li>Packaging specification<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">\n  Available company and product documents can be reviewed through BOWO Electric's<br>\n  <a href=\"https:\/\/bowo-electric.com\/fr\/qualification\/\"><br>\n    qualification and certification page<br>\n  <\/a>.<br>\n  Buyers should confirm which document applies to the exact model included in the<br>\n  quotation.\n<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Manufacturer Experience from Photovoltaic and Energy Storage Discussions<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">\n  During BOWO Electric's participation in<br>\n  <a href=\"https:\/\/bowo-electric.com\/fr\/bowo-electric-showcases-waterproof-electrical-enclosures-at-snec-pves-expo-2026\/\"><br>\n    SNEC PV&amp;ES Expo 2026<br>\n  <\/a>,<br>\n  customer discussions repeatedly focused on enclosure size, cable-entry configuration,<br>\n  DIN-rail installation, outdoor sealing and product customization.\n<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\n  These questions show why project inquiries should include more than a required IP<br>\n  rating. A supplier needs to understand the complete assembly before recommending a<br>\n  standard enclosure or evaluating an OEM modification.\n<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\n  BOWO Electric has manufactured waterproof electrical products since 2017.

A higher rating may be<br>\n  unnecessary for a sheltered installation, while an exposed low-level connection may<br>\n  require additional protection. Installation quality remains important at every rating.\n<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Can cable-gland holes be machined before delivery?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">\n  Yes. Standard enclosures can often be supplied with CNC-machined holes for cable<br>\n  glands, connectors, switches or other components. A dimensioned drawing should be<br>\n  approved before production.\n<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Should a solar distribution box have a transparent cover?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">\n  A transparent cover can make visual inspection of circuit breakers and internal<br>\n  indicators easier. Whether it is required depends on the maintenance procedure,<br>\n  component layout and project specification.\n<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What information is required for a customized enclosure quotation?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">\n  Provide the installation environment, enclosure dimensions, internal layout,<br>\n  cable-entry drawing, material, required protection level, accessories, quantity and<br>\n  destination. Photographs or drawings help the manufacturer evaluate the project more<br>\n  accurately.\n<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Should a sample be approved before mass production?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><br>  Sample approval is recommended when the enclosure includes CNC machining, custom<br><br>  accessories, printing, unusual cable entries or a specific internal component layout.<br><br>  The approved drawing and sample version should be recorded before bulk production.<\/p>\n\n\n\n<div class=\"article-author-box\">\n<h3>About BOWO Electric<\/h3>\n<p>Zhejiang BOWO Electric Co., Ltd. manufactures waterproof junction boxes,<br \/>distribution boxes and related electrical enclosure products for outdoor,<br \/>industrial and OEM applications.
