You disconnected a 240 volt wall heater now connecting the wire to a receptacle Is white wire hot in that case?

User Avatar

Asked by Wiki User

No, the white wire is typically the neutral wire in a 240-volt system. In this case, the black wire is typically the hot wire that carries the current. It's important to verify the wiring with a voltage tester before connecting the wires to the receptacle to ensure proper installation.

Does the ground go with the neutral when installing 3 prong dryer outlet?

User Avatar

Asked by Wiki User

No, the ground and the neutral should not be connected together in the wiring of a 3-prong dryer outlet. The ground wire provides a safe pathway for electricity to dissipate in case of a fault, while the neutral wire carries current back to the electrical panel. Connect the ground wire to the ground terminal and the neutral wire to the neutral terminal in the outlet.

Can you use a compass to detect the currents in wires in the walls near light switches in your home?

User Avatar

Asked by Wiki User

No, a compass cannot be used to detect currents in wires within walls. The magnetic field created by the current in household wiring is not strong enough to be detected by a compass. To detect currents in wires, specialized tools such as a non-contact voltage tester or a multimeter should be used.

Can you use 10-3 with 30 amp breakers at 90 foot to run a 225 amp max arc welder?

User Avatar

Asked by Wiki User

No, using 10-3 wire with 30 amp breakers is not suitable for running a 225 amp arc welder. The wire size and breaker amperage should be appropriately matched to the current requirements of the welder to ensure safety and prevent overheating of the wire. In this case, a larger wire size and breaker amperage would be needed to support the 225 amp maximum draw of the welder.

You have a red box and a black box they are exactly the same size the red box is heavier than the black one what does it tell you about physical properties of the boxes?

User Avatar

Asked by Wiki User

The red box likely has a different material composition than the black box, with the material in the red box likely being denser. This difference in density causes the red box to be heavier despite being the same size as the black box.

What is A mini circuit breaker that responds to shorts or contact with water?

User Avatar

Asked by Wiki User

A ground fault circuit interrupter (GFCI) is a mini circuit breaker that responds to shorts or contact with water. It monitors the flow of electricity in a circuit, and if it detects a ground fault (such as water contacting the electrical system), it automatically shuts off the power to prevent electric shock.

Gas furnace it has 3 switches one n the fan cage and two in the wiring box does anyone what they are for?

The switch on the fan cage is likely the fan switch to control the fan manually. The two switches in the wiring box could be the power switch for the furnace and a safety switch for emergency shutoff. It is important to consult the furnace manual or a professional to confirm the exact purpose of each switch.

Wiring ground silver or gold screw?

User Avatar

Asked by Wiki User

When wiring a three-wire U.S. single or duplex 15 or 20 amp receptacle: GROUNDING (green or bare) wire goes to the green screw. NEUTRAL (white) wire goes to the silver screw. HOT (could be any other color, often black) goes to the brass screw. For a better understanding, check out the Related link PDF shown below. : IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOB

SAFELY AND COMPETENTLY

REFER THIS WORK TO QUALIFIED PROFESSIONALS. : If you do this work yourself, always turn off the power

at the breaker box/fuse panel BEFORE you attempt to do any work AND

always use an electrician's test meter having metal-tipped probes

(not a simple proximity voltage indicator)

to insure the circuit is, in fact, de-energized.
