Yes unless your wiring is old enough to not have a ground. If you can afford it, then run a ground anyways! Grounds are there for your safety!!!
Yes, black is hot, white is neutral, and copper is ground.
Yes, you can still have an electrical fault current on an appliance or the wiring which needs to have a ground return path for personal and equipment safety.
Only if you wanted to fry your hair.for God sake(and yours)buy a new cord to hook up your dryer
There is no switch on an outlet. You can mount an outlet with the ground up or down. Most electricians I know mount the ground down as I do.
Black wire to gold screw, white wire to silver screw, ground to green screw. If you are using a GFIC outlet then the hot wires coming in hook to the Line side of the GFIC receptacle and the wires going out to other receptacles hook to the load side.
each needs a separate 20 amp feed
hook a ground up to your battery and mount it to the amp and hook it up with a few more things and yea you got it man
No. Hook up the power wire first, then the ground wire. The ground wire is what acutually draws the power to the unit. As you will notice the power wont turn on if just the power wire is plugged in..
The neutral bus
to hook up the tach use the hot lead on the disributor and to any good ground wire and if there is a light hook it to the wire on you light switch
The "hot" wire and the neutral wire both carry current (the same amount, in fact) when a load is connected to complete the circuit. The ground wire never carries current except when a fault-to-ground situation occurs. Yes, neutral and ground wires should both be at ground potential, but NO they should not be connected at the outlet.
No. You need a good battery for the voltage and amperage to operate the starter.
