Good day Forum
Do you have any recommendations for fire rated wires to be used in an area experiencing heavy sea blast? the bare copper connections are turning black and corroding.
You might email Mr. Black and see if he has some input:::
OHHH I am not an engineer, so you can discount my reply if you want, and I cannot do math.
Not into electrical can you wax them??
Do a search appears there are products that protect against salt water, just a matter if they can be used on fire alarm systems?
What kind of enclosure are you dealing with? It sounds like the enclosure isn't rated for the environment it's being used in.
This is at a hotel along a beach. Devices even inside rooms are becoming corroded. Nothing was run in weatherproof boxes though.
For the devices inside, confirm with the manufacturer but you could clean the exposed wire / terminals and apply an anti-oxidant compound. The compounds are not weatherproof but should help prevent corrosion in the application you described.
