I have a switch that I would like to put in a workshop in a potentially damp location. It's not going to be outside in the rain, but it's entirely possible that at some point water might get splashed near it.
What's the best way to make this safe? I can't find any outdoor-rated switches like "WR" rated outlets, which was my first thought. Should I put an outdoor recepticle cover over it, like this? I'm not sure if the screw holes will line up in the right place. Or is there some other way to make this switch as safe as possible?
(Bonus question: if I don't want to put a GFCI breaker in my distribution panel, can I just use the load terminals on a GFCI outlet and use that to protect the switch & light?)
Best Answer
If National Electrical Code applies, here's what it has to say...
Which means that if the box containing the switch is not mounted inside the wall, you'll need a weatherproof box.
Once the switch is mounted in the box, you'll need a weatherproof cover. You'll have a couple options here. You can get one with a flip up lid, where the cover has to be flipped up before the switch can be toggled.
There are also covers available that completely encase the switch, and have an external lever that is used to toggle the switch.
Bonus
Yes, you can supply a switch from the Load side of a GFCI receptacle to provide GFCI protection to the switch.
