In any distribution panel there are individual bars for each termination. The ground buss is in direct contact with the metal enclosure. The neutral is isolated from the metal enclosure. The only place where the two come into contact with each other is where a bonding screw protrudes through the neutral bar and into the metal enclosure.
Neutral is connected to ground at the distribution panel, and no where else. Any current flowing on ground downstream of the panel is considered a ground fault.
It may be the GFCI breaker is defective. Make sure it is wired correctly. Neutral to neutral bar and ground to ground bar.
Black & Red are hot, and White is neutral. If it has no place to connect neutral connect neutral to ground.
remember the + side of the speaker basically means neutral, in all electric projects the - is always the live line, so if + means neutral that basically means that ground would also be neutral, speakers dont need ground, so if u wish connect + with neutral on the speaker.
No. The sub panel is wired that same as an ordinary three wire load. The three wire is connected the sub panels terminal points as red to L1, black to L2, white to the neutral bar and the ground wire in the cable set to the ground bar. The one thing that has to be done is the bonding screw that bonds the neutral bus to the panels metallic enclosure has to be removed. The electrical code states that there is only one place that the ground is joined to the neutral bar and that is at the service entrance point into the main distribution panel.
Ground wire can be appropriately bonded to the neutral and cabinet at the service box by connecting the neutral and ground wires from the feeder wires to the neutral bus bar and the ground terminal located on the same cabinet at the service box. White wire (neutral) must be connected to bus bar and bare wire must be connected to ground terminal in the same cabinet.
If you are connecting 120 volts, you connect the black wire to the breaker, white wire to the neutral bar, and ground wire to the ground bar. If you are connecting 240 volts connect the black & white wires to the breaker, & ground wire to the ground bar.
Without more information that appears to be a 240 volt circuit. Red & black would connect to the 240 volt breaker, white connects to the neutral bar, and ground conductor from the ground rods or ground plate connects to the neutral bar. Make sure that the bonding screw is in the neutral bar and it is screwed through to bond the distribution panel enclosure to the neutral bar.
It shouldn't. The open end of a non connected neutral should have the same potential as the voltage feeding the circuit. The only time a voltage will show is when the return neutral is tested with a meter to the neutral bar or the ground return bar. It will then show what the supply voltage to the connected load is. Once this neutral is connected to the neutral bar there will be no voltage shown across the test meter between the neutral and the neutral bar or the ground bar.
Yes, if possible, connect the grounds to the ground bus bar and the neutrals to the other side on the neutral bus bar. This is just in case you ever install a sub panel. It is not a violation of the NEC code to connect them to the same bus bar but IMO it is unprofessional and can cause problems later on.

If there is no ground wire connect the ground wire to the neutral wire.

There is 220 volts between the two poles. If you are running 2 wires (black and white) + ground then you hook black to one pole and white to the other. Put red or black electric tape on each end of the white wire and wrap around wire for 3 inches or so next to the connection so the next person will be able to see that the wire is hot and not a neutral.

Purchase a ground rod from an electrical supply. Drive it into the ground just outside where your service is located. Install a ground cable from the neutral bar in the fuse box to the ground rod and clamp both ends. Voila, you have done it!
