I order to do this all the wire need to be replace with three wire.
Yes, you can wire a three-way switch using 12-2 wire, which consists of two insulated conductors and a ground wire. In this setup, you would typically use one of the hot wires for the switch and the other for the traveler wires connecting the two switches. Ensure that the circuit is properly grounded and that you follow local electrical codes for safety. Always turn off the power before beginning any electrical work.
Green wire must be grounded for safety. The two white wires are phase and neutral. You can discover which one is the hot wire by using a mulltimeter. But there is no needing to discover it. About the green wire only an electrician can install it properly. It can be joined to the neutral wire, but it is not advisable for any electrical device. The correct procedure is to connect the ground wire on the recommended manner. Normally lamps do not need to be grounded.
No, 14-2 wire is typically used for lighting circuits in residential electrical installations. For outlets, it is recommended to use 12-2 wire to handle the higher electrical load.
The recommended wire size for a 125A electrical circuit is typically 2/0 AWG copper wire.
The recommended wire size for a 200A electrical circuit is typically 2/0 AWG copper wire.
This is the most common type of home electrical wire that is installed for general purpose electrical circuits, also known as Type NM or Non-Metallic sheathed cable made up of at least one pair of insulated wire conductors and one bare wire used for the ground conductor. This kind of wire have 3 sizes, PDX 14/2, PDX 12/2, and PDX 10/2. The ground conductor is bonded throughout the home to maintain a contiguous grounded system which originates back at the Main Service Panel. Most electrician know this kind of wire as Loomex, Romex, and PDX.
The recommended wire size for a 125 amp electrical circuit is typically 2/0 AWG copper wire.
The recommended wire size for a 200 amp electrical circuit is typically 2/0 or 3/0 gauge wire.
No, it is not recommended to use 12/2 wire for lights in your electrical installation. It is typically used for general household outlets and appliances, while 14/2 wire is more suitable for lighting circuits.
No, it is not recommended to use 12/2 wire for outlets in your electrical installation. It is typically used for lighting circuits and not outlets, which usually require 14/2 or 12/3 wire for proper installation.
The recommended wire size for a 100 amp aluminum electrical circuit is typically 2 AWG (American Wire Gauge).
The resistance can be changed in following two ways: 1.By change the length of the wire. 2.By changing the area of cross section of the wire.
