ECN Forum Forums General Topics of the Trade General Discussion Area Outlet in Garage for Table Saw

On a 30 amp circuit (10/3 romex and 30 amp breaker), supplying a single outlet in a garage (for a table saw), can a 15 or 20 amp receptacle be used (to match the 15 amp 220 volt plug on the saw), or must it be rated to the full current rating of the circuit, i.e., 30 amp receptacle?

210.21 Outlet Devices.
(B) Receptacles.
(1) Single Receptacle on an Individual Branch Circuit. A single receptacle installed on an individual branch circuit shall have an ampere rating not less than that of the branch circuit.

You can remove the 30 amp breaker, install a 20 amp, keep the wiring and install a 20 amp receptacle (look for a commercial back wire that will accept 10 awg).

In addition to this, Table 210.21(B)(3) requires a 30 amp receptacle on a 30 amp ckt. regardless of how many receptacles are installed.
