I recently got a circuit added to my spare room to grow some tomatos, the lighting I am going to be using is 8amp on each plug, I noticed the electrician didnt install a 20A rated receptacle with the side blade but installed a 15amp instead. I am wondering if this is safe, it is the only receptacle on the line. Pretty simple fix to swap it out if need be
Yes, that is fine.
Normally, the rule is that the socket size must match the breaker size. However there are two exceptions:
- 15A receptacles are allowed on 20A circuits, as long as there are at least 2 sockets on the circuit. This is supported by a UL rule that requires the internal wiring of all 15A sockets certify for 20A passthru.
- 50A receptacles are allowed on 40A circuits because nobody makes a 40A receptacle.
