2 Neutral Wires

One 2 core earth cable takes live and neutral to the switch back box a second cable takes.

2 neutral wires. I found 2 white and 2 black wires connected to the old receptacle using separate screw terminals. 2 black hot wires. Most wiring in your home is 120v either 1 or 2. The hot and neutral lines should be two distinct colors but the colors can vary for the different wires.

Since the neutral has a voltage potential of 0 it is significantly safer to work with than the hot wires a and b. Identifying electrical wiring properly is an important step when replacing a light fixture installing an outlet or handling other electrical work. The neutral wire forms a part of the live circuit along with the hot wire. This is a safety feature in case the hot or neutral wires somehow come in contact with metal parts.

The grounded electrode conductor. 1 copper ground wire. My new receptacle only has 1 hot and 1 neutral and 1 ground terminals. Connect b to neutral 120v.

2 unused white neutral wires. A smart switch can simply tie into the white neutral wires to complete the circuit and get a source of power to keep the radios in the switch working at all times. This fluctuation causes the wires to slightly expand and contract and over time the connection gradually becomes loose. Neutral conductor of a 3 phase 4 wire system and the middle conductor of a 2 phase 3 wire system to have minimum two separate and distinct earth connections with a minimum of two different earth electrodes to have the earth resistance to a satisfactory value.

Hot side tab is not broken neutral side has broken tab. The neutral wire the purpose of the neutral wire is to complete the 120volt ac circuit by providing the path back to the electrical panel where the neutral wire is connected and bonded to the earth ground. Once in an awhile if the connection becomes loose enough you may hear a snapping or sizzling sound. The neutral is an insulated wire because it is part of the circuit which flows electrical current.

The earth electrodes to be inter connected to reduce earth resistance. An example of a 3 wire lighting circuit is shown in figure 2. One example of a 3 wire lighting system. In contrast the ground wire is connected to any metal parts in an appliance such as a microwave oven or coffee pot.

Do i need to use the short neutral that came with the new switch and do something with it if so specific instructions are appreciated. The 3 wire system is less common than the 2 wire system it includes a neutral at the switch as well as the live and switched live wires. Option 1 run a neutral wire if you want to use smart switches and don t have a neutral wire in your switch box you can hire an electrician to run a neutral wire between the light fixture and the switch. Connect a to neutral 120v.

One is that the wires may be from two different circuits and that the loading of these two neutral wires may fluctuate. I m wondering if i can just randomly pick one of the two neutrals and directly connect it to the new switch.
