thanks brother i already told me electrician to attach new 20a seperate circuit for emotiva xpa-5..

you cud plan to have a seperate 15amp line for your power amp

A line for your onkyo + sources (BDP ,CDP) + Projector (as these dont consume much power)

And a seperate line for your 2 subs

also do chk the earthing for all lines

hey brother today just electrician arrives and he says i don't have earthing in my house so he'll do earthing too and i already install 32amp circuit separate line for xpa-5 and also in future if i want to add xpa-2 the same line works for it
