30 Amp Breaker Question

I want to move my system into another room. The room has three outlets and a lighting fixture. The circuit traces back to a 30 amp breaker in the box. Is there any problem using a 30 amp breker circuit with audio gear? I know a 20 amp dedicated line is better, and that will come later.
check your wireing. 30 amp breakers are usually 220v. and
require 10g. wire.if you have 12 or 14g. wireing, replace that breaker with a 15 or 20 amp as per wire size. you are
looking at a potential disaster if you don't have the
proper wires.it's just not worth it.use a dedicated line
if you feel you need it, but make sure you check that
wireing.breakers are for safety. remember that.
Hi, why do you say a 20 amp is better. I just installed a dedicated line and went with a 30 amp breaker and that was to code. We used 10 gage 3 wire with a ground and broke the tabs on the hot side so each is its own circuit.Hope this is right. Sounds nice.
Maybe I shouldn't have said better. all of the suggestions I see for dedicated line is to use 20 amp breakers, is all.

The breaker is a 30 amp breaker, labelled as such on service panel. It is not 220v, measures a steady 122.7 on my Rat Shack voltmeter. Not sure the guage of wire, guess I will have to check.
Holy shit, Johnhifi! What are you driving your loudspeakers with, an ARC welder?!
Branch wiring to to 120-volt lights and receptacles have to be on a 15 or 20-amp circuit breaker, but the wire can be any size greater than #12. That's the code - whether you choose to heed it or not is your business. General-purpose receptacles are rated for 20-amps, which is why the 20-amp max breaker size.
Agree with Johnhifi, but like to add that the prescribed breaker per code is meant to protect the correct sized WIRING that comes after it, from overheating and possibly causing a fire. An equipment failure current might not be high enough to tripout a 30A or even 20A cb unless there is a direct shortcircuit or something near that to be detected and act upon by the cb.

Simply put an UNPROTECTED equipment could well continue to FRY as long as the said wiring and the supplying cb can happily supply the current. So its very important to note that the correct fuse rating at the back of the equipment is the sole protection against such disaster happening, and should never be replaced with a higher rating. However to prevent frequent nuisance fuse blowoff, especially for power transformer turn-on surge so typical of our audio equipment, some maker do specify a T type fuse which delay a fraction before blow off, compared to the quick blow F (general purpose) type fuse of a same current rating.

Timo, I think its okay even to use a arc welder-sized input wiring as long as the equipment's FUSE PROTECTION are correctly in place. A 30A wiring compared to 20A will have less voltage variation seen at equipment power input plug between low and full demand. But how does all this affect the SOUND?

To each his own preference where he wants to upgrade first. My own experience in more Copper "investment" upfront resulted in a bigger sounding, less hesitant, more lively sound compared to that previously. Of course I also have in place all the other gears like powerdistributor/filter, powercords etc. This effect is evident even for my 28W/ch SET amp! What about those considerably much higher powered Audiogoners gears. Try figure that out.
The 30 amp breaker you have is ok as long as you have the correct wire size, 14 guage - 15 amp breaker, 12 guage - 20 amp breaker, 10 guage - 30 amp breaker.
This is the wire size and breaker size per unified building codes and only for copper wire.
It sounds like you have a branch circuit and some one may have swapped breaker out, you need to find out wire size and put correct breaker in. I run two 10 guage conductors for each hot, nuetral and ground with 30 amp breakers, the two 10 guage wires doubled up is about 7 guage wire but I have amps that put out around 1600 watts each! Happy Listening!
I recently bought this house, and I find that there is, indeed, 10 gauge wire. What I didn't intially realize is that, in addition to the outlets and interior lighting fixture, there are THREE exterior fllodlights on the same circuit. Time to condense and separate! :-0
