Yet nowhere within the receptical would it conduct 30 amps because the current is added at the conducting wire. In theory, if heat dissipation isn't an issue, you could install a 15 amp rated duplex outlet on a 30 amp circuit and be just as safe because the top could handle 15 amps and the bottom could handle 15 amps. The current conducted through the front of the outlet is added to the 20 amp branch total at the wire, not within the outlet itself. You are allowed to use a 15 amp rated outlet on a 20 amp circuit simply because it is expected that the cord that's plugged into the outlet should not exceed 15 amps (by code). "Apparently a 15A receptacle is safe to use 20A" Which means you can install a single 15 Amp duplex receptacle on a 20 ampere circuit, without violating this code. So a duplex receptacle would be considered two receptacles, according to this definition. A multiple receptacle is two or more contact devices on the same Is a single contact device with no other contact device on the same A receptacle is a contact device installed at the outlet for the connection of an attachment plug. Keep in mind that NEC defines a receptacle as follows. This is to allow You to have multiple devices plugged in drawing less than 15 Amps each, but the total draw on the circuit may be greater than 15 Amps. If there are multiple receptacles on a 20 Amp circuit, the receptacles can be either 15 or 20 Amp (aside from the exceptions). If it is a single receptacle on a 20 Amp circuit, it must be a 20 Amp receptacle (aside from the 2 exceptions).
