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.
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.
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.
It is called an Electromagnet, when disconnected, it loses it's magnetism.
The bar magnet and the electromagnet act identical. The difference being a electromagnet is a coil of wire that has a power source connect to both ends, this energizes the coil with an electromagnetic field.
One would be able to purchase a tow bar for the Ford Transit either through the internet with online retailers or through one's local dealership from which they bought the Ford Transit.
I assume you mean you are wiring a 220 volt circuit. You will install a 220 volt double pole breaker of the correct size for the circuit. An example would be for an electric dryer that requires a 30 amp double pole breaker wired with 10/3 wire. You connect the Red & Black wires to the breaker. One on each screw. You now connect the White wire to the neutral bus bar in the service panel. Then connect the bare copper ground wire to the ground bus bar in the service panel. At the dryer outlet connect the black & red to the hot screws, white to the neutral, and ground to ground. They will be labeled on the back of the outlet.
If you wrap a length of wire around the iron bar then pass a current through the wire, the bar will become magnetised.
Black. wire goes to breaker, white wire goes to neutral bar, and copper wire goes to ground bar.
Front = 5 bar Rear = 4,5 bar
There should be two outputs on the 30 A breaker. You will need 10 AWG wire with 3-conductors and ground. Typically the wire colors will be Black, Red, White and (Green or bare). Connect black to one output of breaker and red to other output. Connect white to the white buss bar in main panel and green/bare to ground buss bar. At heater end connect the red and black to the 240 V leads, white to white and green/bare to the heater case.
