Hi,I am in the process of wiring a small work shop, believe it or not it has run on an extention cord from house for three years!.I have 4 110 recepticles, 5 flourecent shop lights,and a 2hp 14amp compressor 100 max psi. I plan to feed from main box at house with 14/2 with ground, sub box with two breakers,both 20 amp,one will be dedicated to compressor only,the other to light's/recepticles..my questestion's : will the 14 gauge carry the load,and what size breaker should I use at main(at house) would 20 amp be enough or should I go higher since I have the two 20amps at sub panel? it is only a hobby shop and no two electrical tools will be used at same time..the compressor I mentioned(new) gas been kicking breaker since I bought it (last week) and kicks breaker when it cycles...thank's

I am adding two 20 amp circuits for my two bathrooms. I have a Murray Breaker panel and need some more room for common and ground wires. The instructions on a Cutler-Hammer ground bar kit show mounting it and no connection to the existing neutral bar. My thoughts are to mount the extension bar to the panel box with the machine screws provided and run a #4 wire from the neutral bar to the new extension bar. When I have the inspector for the rough inspection I will show him what I plan but would like opinions. Thanks for the help.
