What color is the grounding wire in armored cable?
The grounding wire in armored cable is typically green or sometimes bare copper. It is used to provide a path for electrical currents to safely discharge in the event of a fault, protecting people and equipment.
What is the minimum ground wire size for a 20 amp 110 volt circuit?
The ground wire in a two or three conductor #12 cable is a #14 bare ground wire.
What was used before romex wire became available?
Before Romex wire became available, cloth-covered wire, knob-and-tube wiring, and armored cable (BX) were commonly used for electrical wiring in residential buildings.
Can a 125 volt cable power a 120 volt piece of equipment?
The first thing we have to do is clarify the question. A cable rating of 125 volts is an insulation rating of the wire. Like wire with ratings of 300 volts, 600 volts and 1000 volts these are the highest allowable voltages that can be applied. A wire that is rated for 300 volts is good for 120 volts, 240 volts and 277 volts. At test research facilities, equipment is tested to destruction. The label that is given to wire as a result of the tests is the highest safest voltages that can be applied to that particular wire. So when you see a wire that has a label stating that it is rated for 300 volts it means that any voltage under and up to 300 volts is safe to apply. So to answer the question yes, the 125 volt insulation rating on the cable can be used to supply a source of 120 volts to a 120 volt rated piece of equipment.
Can you use an existing 300 volt cable to wire in a dryer plug?
The voltage insulation rating is not the factor that cables need to determine how much current that a wire can carry. Most home wiring is rated at 300 volts. A 3C #10 cable is rated for 30 amps. This is the cable that is usually used on dryer connections.
