It simply means that the ground wire is not grounded. There are two HOT wires and the unshielded copper ground wire which should be connected some how to the earth (ie. grounded)
In industrial wiring 'three phase' green or bare copper is the norm for a ground. In home wiring 220/110 single phase, bare copper is the ground
The ground wire in a two or three conductor #12 cable is a #14 bare ground wire.
To wire a 230 volt contactor with a 110 volt coil, you need to connect the 110 volt power supply to one terminal of the coil and the neutral wire to the other terminal of the coil. Ensure that the contactor is rated for use with a 110 volt control circuit. Additionally, verify the wiring diagram provided with the contactor for proper connection details.
No, you should not connect a 110-volt space heater to 220-volt wiring as it will likely cause the heater to burn out due to the higher voltage. You should always match the voltage requirements of the appliance to the electrical supply to prevent damage.
The American system is 110 Volts and the UK (plus some other EU countries) are about 240 Volts. The formula is Volts X Amps = Watts. Don't panic, that's as hard as it gets. The problem is this, that for 240 Volts a current of .25 Amps is needed to light a 60 Watt bulb (240 X .25 = 60). At 110 Volts this would be about 110 X .5 = 60 giving over twice the Amps for the same Watts. The more Amps, the heavier the wires needed to carry the power. So, to be safe the fitting would have to be rewired. If in doubt contact an experienced electrician to rewire it for you. Better a few dollars than dialling 911 because the house is on fire!

On a 110 volt circuit, Black is hot, White is neutral, Green or bare Copper is ground. . Connect Black to the gold screw, White to the silver screw, and bare copper ground to the Green ground screw on the receptacle. On a 220 Volt circuit Black & Red are both hot, each carrying 110 volts for a total of 220. White is Neutral and ground is Green or bare copper.
i think its the red and black wires
Yes but I would not advise it. Get 110 volts somewhere else.
green
doesn't matter you get to choose
your house has 220 you must use a 2 pole breaker. your wiring will change ,not a do it your selfer call someone
Read the name plate on the motor for wiring diagram.
Hot, neutral and ground.
It is between 100 and 110 metres in length.
It is dangerous to connect 110 v equipment to a 240 v system. See an electrician before you do anything.
It would be best if you contacted a qualified electrician to resolve any questions about house wiring. There is a real potential for serious injury, death to you or others, and damage to your house.
