Take a look at the mains fuse rating on your amp and you will see that it's much less than 20-amp. That limits the amperage draw to the amplifier and it would make no difference if the breaker and wiring to the amp handles 20, 30 or whatever amps.
home circuit breaker - good idea or not to increase to higher amp fuse?
Hi all, breaking off to a separate discussion. While fixing some electrical stuff at home, my electrician informed me that my circuit breaker fuse for my music room area is 20amp. I'm wondering if upgrading the home circuit break fuse from 20 to 30 or 40amp fuse would improve current flow to my hifi amp. Has anyone done something like this before at home?
