View Full Version : Where do you use 20A circuits?

Are 20A circuits really necessary in general?

I know it is cheaper to do 20A GFCI rather than 15A split GFCI in the kitchen.

Outside of the kitchen is it better practice to use isolated 15A circuits for larger load outlets or are there household (non-kitchen) appliances that require 20A outlets?

The way I read the code it seems to imply it is better to provide isolated 15A circuits and less outlets per circuit than use 20A circuits. For example CEC says only 15A for lights and I understand that it is good practice to share a load between outlets and lights so that would imply no 20A in general.

What is your opinion on using 20A circuits? Do you try and avoid them or do you use them alot?

Anyone put in a 15A circuit only to wish it had been 20A?

Thanks

Greg

I don't have a clue where the CEC might mandate 20 amp circuits, but I wire all the receptacles on 20 amp circuits and only use 15 amp circuits for the lighting. Using 15 amp circuits for receptacles is "cutting corners" in my mind.

I believe the CEC does not allow 20 amp to be used for lighting.

u r allowed to use 20A in other than dwelling units, if the input voltage does not exceed 347V
