A waterproof junction box is a device for connecting and distributing electricity in wet or harsh environments. Here are some things to think about when buying a waterproof junction box:

The waterproof rating is an important factor when choosing a waterproof distribution box. Choose the right waterproof grade, such as IP65 or IP66. IP65 means it is dustproof and resistant to water spray. IP66 means it is dustproof and resistant to strong water spray. Choose the right waterproof grade for your needs.

Material and durability: The waterproof distribution box should be made of high-quality weather-resistant materials to ensure it is waterproof and durable.

Capacity and size: Choose the right size and capacity for your distribution box. The box should have enough space for the wires and other devices, and to keep the wires safe and ventilated.

Sealing performance: Waterproof boxes should be sealed to keep out moisture, dust and other contaminants. The box should have a rubber seal that seals when closed.

Ease of installation: Choose a waterproof distribution box that is easy to install and use. Some breakout boxes come with brackets or screws for easy wall mounting.

Cable inlets and outlets: Watertight breakout boxes should have multiple inlets and outlets for wires. Seals should be used on inlets and outlets to keep water out.

Safety certifications: Choose a waterproof breakout box with the right certifications. This helps ensure the product is safe and meets the relevant standards.

When buying waterproof distribution boxes, think about all the above factors and choose the right product for the job.
