GE 30 amp slim type breaker

[phil kaznowski]

I inspected a GE panel yesterday that had a single 30 amp slim type breaker supplying a standard 3 prong 4 receptacle outlet. I was unable to locate anything in the NEC and have never seen this before except to a dedicated single outlet for an appliance or tool.

Any help is appreciated!

supplying a standard 3 prong 4 receptacle outlet.

Phil,

I suspect you are referring to double-gang duplex grounded receptacle outlets (3 prong = grounding type and 4 receptacle = 2 duplex).

There is nothing wrong with that provided that the breaker is in the appropriate space in the panel. Typically, they manufacturer specifies which spaces are allowed to have those breakers installed, and it could be any of all the spaces, or it could be limited to just certain spaces.

You would need to look at the wiring schematic on the panel (typically on the cover) and read what it states.

Sounds like overfusing if wire is 12 or 14 gauge. And regular 120v receptacle is rated only for 15 or 20 amps.

That is true, I had not processed that part through my head.

While 'there could be 4 - 30 amp receptacles, if they are duplex as I suggested, they would be 15 amp or 20 amp.

The only time I see a 120v 30 amp receptacle is for a window AC that was rated as such and is long gone. On 10 ga.

Good catch Phil...

A 30 amp breaker needs 30 amp wire and a 30 amp receptacle. The receptacle also needs to be the correct voltage configuration.
