Am I hearing things?

I looked downstairs in the electrical panel and no and nowhere is there a 15, 20, 25, or 30.marked on the breakers. Is there a secret code electricians use?

The ampere rating should be on the ON/OFF breaker handle. Sometimes it’s printed on the face of the breaker. The ampere rating should be visible on the front of the breaker for the user to see. What manufacture electrical panel do you have?

Example.
20 amp breaker.

Did you find the breaker/space panel numbers for the 2 dedicated circuits for your audio system?

What to look for. In the majority cases the odd numbers are on the left side of the panel and the even numbers on the right side.

Example.
Single phase 120/240 Volt panel.
L = Line, Leg, Bus.


Left side ...........................................Right side

L1.. breaker/space #1) ........ breaker/space #2)

L2 .. breaker/space #3) ......... Breaker/space #4)

L1 .. #5) ............................................... #6)

L2 .. #7) ............................................... #8)

L1 .. #9) ............................................... #10)

L2 .. 11) ............................................... #12)

And so on down each side of the panel

Yes the 25 was right on the swtich. I overlooked it big time

I use a label maker to mark each breaker. One thing i dicovered is the 20 amp single outlet I use from the kitchen to power my stereo has a COMMON NEUTRAL* with another 20 amp circuit which is on the other leg and powers the frig and countertop duplex (toaster over and toaster) I looked up info about common neutral. and seems to be not a big deal unless not known. (ie working on one with the other still alive) Is there any other issues I should know for a COMMON NEUTRAL*                                                     (*For those in the dark a common neutral means one neutral line for two hot lines, with the hot line on different breakers)On The Furutech it is nice I can squeeze the two neutral wire parts in the wall into the same hole. So no gap or running the other line neutral’s power if any, through the Furutech outlet.There is no noticeable noise in my system from the other line. And I have been using this 20 amp outlet for 7 years or more. I just was realizing what a COMMON GROUND was when reading up on it.

Is there any other issues I should know for a COMMON NEUTRAL*

Hi Elizabeth,

The first thing I would wonder is if the neutral wiring that is common to the two circuits is rated to be able to conduct 40 amps, which it would have to if and when 20 amps is being drawn from each of the circuits.

Also, I can envision that sort of arrangement being conducive to ground loop issues in some systems, because the unequal currents in the hot and neutral conductors, and their differing distances from the safety ground conductors, would tend to increase hum and noise voltages that are electromagnetically induced in the safety grounds. (I’m assuming that there are safety ground conductors, and that they are physically close to either the hot or neutral conductors)

Jim (Jea48) is more knowledgeable about this kind of thing than I am, though, especially from a code standpoint. We’ll see what he has to say.

Best regards,

Elizabeth  one other thing you might look for the two breakers that share the common neutral need to be ganged. 2  20amp breakers with a common neutral will trip like any other 20amp breaker they won't draw anywhere close to 40amps. The load wouldn't be balanced on the neutral which is what would trip the breaker actually breakers they are suppose to be ganged with the hot on seperate phases.
