Frequently Asked Questions
What is a marine brass junction box used for?
A marine brass junction box provides a safe, weatherproof enclosure for splicing and terminating electrical cables in shipboard and offshore installations. It protects connections from moisture, salt spray, and mechanical damage.
Is this junction box suitable for underwater use?
No, the IP66 rating means it is protected against powerful water jets and heavy seas, but it is not designed for permanent submersion. For underwater applications, a different IP68-rated enclosure would be required.
What wire sizes can be terminated in the 5-way terminal block?
The terminal block accepts conductors up to 10 AWG (6 mm²) with a maximum rated current of 30A and voltage of 440V AC/DC.
Can I install this junction box on an aluminum or steel bulkhead?
Yes, the box features brass mounting studs that are compatible with standard marine brackets. For aluminum hulls, use appropriate isolation gaskets to prevent galvanic corrosion.
