15amp outlet on 20amp circuit??
 
A while back, I had an electrician install a new 20amp circuit in my garage. I noticed last night that he used regular 15 amp duplex receptacles, instead of the ones with the 'T'-shaped prongs. Even the GFCI recep is 15-amp.

Since there are only 3 of them, should I replaced them, or leave them as is? I imagine if I try to pull 20 amps through one of them, they may burn up? Is this true?

Also, there is one switch on the circuit for a couple 4' fluorescent fixtures. Should I make sure this switch is rated at 20-amps also??? Even though it is only powering four 4' t-12 bulbs?

not true. His method is correct. on 20 amp circuits using a 15 or 20 amp plug is by code and perfectly safe. 20 amp outlets are used primarily for commercial job.

Yup, as stated 15a are rated 20a pass thru
A duplex receptacle is rated to be installed on a 20a circuit

A single 15a receptacle can't be installed

So if I'm understanding correctly, the (2) 15a duplex receps, and (1) 15a GFCI recep are perfectly fine on the 20a 12g circuit. So I don't have to replace these. That makes me happy!

What about the 15a switch for the lights? Are these rated for 20a pass-through as well?

This topic should be made a sticky, seems like it comes up every few days.

yes.. code says "devices" which means receptacles and switches

As does the question of how many outlets can be put on one circuit.

I hope you don't plan on having 20 amps worth of lighting :laughing: j/k... you are fine... it's pretty standard pratice to have 15amp switches and recepticals (duplex ones) on a 20amp circuit... no single one will ever pull 20amps.. and if it does you probably have a different plug that wont fit into the 15amp outlet anyways

Might as well answer that one too just to stop the next one :laughing:

Good point :)

No limit in the US. I believe Canada has a limit.

we usually limit ourself to 8 devices on a 20 amp circuit just to be safe :) switches + outlets combined

In Canada
Lighting must be on a 15 amp circuit. Not permitted on 20 amp circuits.
20 amp circuits require 20 amp T slot receptacles.
Limit if 12 outlets (lights, receptacles, fans etc.) per circuit unless known load (example - lights only) is connected.

Maybe a sticky with a FAQ is a good idea? It probably would have come in handy for a lot of people (myself included).
