Can you use both 15 amp and 20 outlets on the same circuit?

Answer 1

No. You need 20 amp receptacles. ( if a single receptacle on an individual brach circuit NEC 210.21 (B)(1) )

Yes you can use a 15 amp receptacles on a 20 amp breaker in the states but not in Canada. ( branch circuit supplying two or more receptacle NEC 210.21(B)(3) )

15 amp receptacle on a 20 amp circuit is not code, partly because 20 amp circuits use #10 ga wire, which does not fit unto a 15 amp receptacle,(can be forced but lots of work.) Also a 15 amp receptacle will not take the 18 amps continuios that a 20 amp recep. will. ( It is code, see above. 14 awg = 15 amp, 12 awg = 20 amp, 10 awg = 30 amp )

20 amp wire is 12 gauge not 10

Yes you can use 15A outlets and swithes on 20 amp breakers they are UL listed for 20 amp even if they are stamped for 15A as long as the wire is 12ga to. ( NEC Table 210.21 (B)(3) )

Answer 2

It is generally not recommended to mix 15 amp and 20 amp outlets on the same circuit because it can create a safety hazard. If the circuit is protected by a 15 amp breaker, using a 20 amp outlet could lead to overheating and potentially cause a fire. It's best to match the outlet amperage with the circuit breaker amperage for safety and code compliance.

Answer 3

In Canada there shall be not more that 12 outlets on any 2 wire branch circuit. Such outlets shall be considered to be rated at not more that 1 amp per outlet. Where the connected load is known, the number of outlets may exceed 12 providing the load current does not exceed 80 % of the rating of the over current device protecting the circuit.

Answer 4

In the United States this is acceptable provided it is at least a duplex receptacle or it is not the only receptacle on the circuit. A 15A receptacle will only allow devices rated at 15A or less to be plugged into them.

Answer 5

Not a good idea. Match the devices to the rating of the breaker protecting the circuit.

Answer 6

Yes. A higher rating is allowed.
