Is it OK to mix 15A and 20A receptacles on a 20A circuit?
Suppose I put a 20A GFCI as the first receptacle, and put 10
15A non-GFCI receptacle downstream, protected by the 1st 20A GFCI, will GFCI will be effective?What about we put 1st as 15A GFCI, followed by a mix of 20A and 15A receptacles protected by 1st GFCI. Will that cause problems?
Are they code vilation?
My builder put 1st receptacle as 15A GFCI, protecting a few non GFCI 15A downstream in the kitchen, in several of 20A circuits. So using 15A all the way through a 20A circuit is OK, I suppose.
