How and where do you connect the white wire from the shunt breake to the electrical panel?
The white wire would go to the neutral bar. Just be sure of the shunt trip voltage required for the breaker and land the white wire on the appropriate neutral bar in the correct panel.
How do you hook up the distribution panel box with red white black and ground wires?
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.
Why is it that when you touch the neutral in a box that is not connect to the panel cause the test light to come when touching the power wire?
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.
Why do white wire mark 120v?
Because the white wire on a 120 volt circuit is the neutral wire that is connected to the silver screw on outlets and switches. It is connected to the neutral bar in the service panel.
How do you make floating ground in 100 amp sub panel Sub panel 30' from main panel and is grded to 2nd 10' rod wired to 1st 10' rod at the main panel. GFCI bkrs are nuisance tripping in bsmt location?
If the sub panel is in the same building remove the bonding screw that bonds the neutral bar to the panels enclosure. Remove the ground from the second ground rod. The sub panel is grounded by the ground wire from the sub panel's feeder. If the panel is separate from the main building treat the sub panel as a separate service. It will need its own ground rods and ground wire from the rods to the neutral bar of the sub panel. Leave the bonding screw in. There will be no ground wire in the conduit between the two services.
