I found that idle GFCI receptacles are warmer than the wall they attached to. Is it OK?
- They contain sensing and logic circuitry inside, so they consume a bit of power themselves. Since power consumption (no matter how small, and costing virtually nothing) translates directly to heat production, it's understandable that they'll be a little warmer than the surrounding area. Significantly warmer, though, and there may be a problem. Be especially mindful of any outlets that get significantly warm when a load is plugged into an outlet! If an outlet with nothing plugged into it gets warm, it may be part of a chain with a weak connection, and should be investigated. --18.104.22.168 (talk) 20:29, 10 January 2017 (UTC)
