Currently, in my kitchen I have a 20amp GFCI receptacle (faceplate only accepts 15amp plugs but back says it is 20 amp rated) off of that GFCI outlet there are 3 15amp receptacles, one is for a garbage disposal, the other 2 are at counter top level for usage. The breaker for the kitchen is 20amps. I have purchased two new 20amp outlets with USB charger capability for phones etc.
Is it okay to have the two receptacles at counter level be 20amp and the disposal be on a 15amp receptacle or should I return the new 20amp receptacles and install 15amp ones?
Not sure if it is correct to have both 15amp and 20amp receptacles off of the 20amp GFCI.
