Due to the moist environment, we recommend using exterior rated light sockets and outlets.
It's best to surface mount those outlets inside of your cooler. If they are recessed into the wall (insulation) they can create an area where condensation can form, right in your outlet!
Take extra care to seal up perforations made by wires coming into the cooler! A vacuum effect can be caused by the warm outside air being sucked in through the back of the outlet box, by the cold cooler air. This can result in moisture gathering and could cause the circuit to trip.
- Take the cover off the outlet
- Find where the wire enters the back of the outlet box
- Using silicone caulk seal any gap where the wires enter the box so no air can move through
- Replace the cover and thats it!
Note: Besides silicone caulk, clay or feldspar can be used to seal up the gap
