creekmaster10-2 use silver paste to coat the wire ends before attaching to breaker ,better yet
would
be to install breaker panel sub box near where it enters wall and use a
grounding rod driven in to the ground 12' 5/8" dia.,then you eliminate
ground interference from main supply and of course use a audiophile
outlet preferably quadplex and also use silver paste with the connection Oh no, that's a violation of the NEC. All grounds must be bonded together at the service panel; anything less than that is potentially dangerous.
As for the silver paste, I'm not sure that meets code, either. Whether it does or not, I don't think it's a good idea. You want clean, tight electrical connections. |
perazzi28 is correct. #12 wire is rated for 20 amps and #10 is rated for 30 amps. If you use a 20 amp breaker it will trip at 85% of rating so what is the point of going to #10. Run a 12/3 romex that is a neutral with two lines and a ground. This will give you two dedicated 20 amp cicuits with one run. Same labor cost. By the way lots of us in the electrical fields are also audiophiles. |
Jea48, the bare wire is the ground. It is connected to the ground bar in the panel and at the outlet it is connected to the box and outlet ground screw
|
Here's a thought - if you have the space, consider a sub-panel adjacent to your rack depending on where the equipment is located from an aesthetic stand-point.
I added a dedicated 60amp sub-panel using 6-gauge in its own conduit from the main panel. That opens up the option of 240 volt power conditioners at the rack which is nice and very short runs from the panel to the outlets.
I grounded the sub-panel separate from the main panel using a grounding plate buried outside connected with 6-gauge grounding wire. Good fun. |
cerberus79#12 wire is rated for 20 amps and #10 is rated for 30 amps.
If you use a 20 amp breaker it will trip at 85% of rating so what is
the point of going to #10. Derating the wire will reduce voltage drop. The calculation of the proper gauge wire for a given amperage hinges on the distance of the wire, so you can't quite say, "
#12 wire is rated for 20 amps," although it is generally true.
