What else can I help you with?
Why are circuit symbols used when drawing electric circuits?
It is often necessary to wire crossing
Can one use 1 circuit of a 3 wire plus ground 2 circuit cable as a GFI circuit with the other as a lighting circuit?
A GFCI can not be used on a three wire branch circuit. It has to be on a single two wire circuit.
Are all 480 Volt light fixtures 3 phase or are some single phase?
I do not believe any lighting fixtures of any voltage have ever been made to work off of three-phase circuits. Light Fixtures are always single-phase 2-wire circuits In the USA the standard voltages for branch circuits are: 120, 208, 240, 277 or 480 The light fixture must be rated to match whichever field voltage is being used. Some light fixtures are made multi-rated so they can be used on more than one circuit voltage
If you overload an oulet by plugging into many things.whan can happen?
The "correct" answer is, wire in more circuits with more outlets. There may be several ways to work around the issue, but the best and safest is to add circuits rather than using plug strips and extension cords.
Are wire wound resistors used in parallel circuits?
Can be. Wire wound resistors might take more power, or offer better precision, or custom resistance values. Wherever, whenever those features are desirable, whether its a series or parallell circuit, a wire wound resistor might be used.
What is the right circuit break to be used for lighting circuits?
Usually 15A or 20A, but it depends on the wire used.
Can you run 14 gauge wire off 12 wire to a receptical?
No, you can never mix wire sizes in a circuit.
What is the smallest size wire that can be installed in a parallel permitted by the nec?
The National Electrical Code (NEC) permits a minimum wire size of 14 AWG for general lighting and receptacle circuits in parallel installations.
What is THHN wire suitable for?
THHN wire is suitable for use in dry and damp locations for general purpose wiring in residential, commercial, and industrial buildings. It is commonly used for power distribution, lighting, and control circuits.
Can 14-2 wire be used for outlets in a residential electrical installation?
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.
Can a single duplex receptical be wired for 120 volts and a second single duplex receptical be wired for 220 volts if they both reside in the same two gang electrical box?
Yes, the feeder will have to be a three wire cable.
What is 14 gauge wire used for in electrical applications?
14 gauge wire is commonly used for general household electrical wiring, such as lighting circuits and outlets. It is suitable for carrying moderate amounts of electrical current safely.
Can I use 12/2 wire for lights in my electrical installation?
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.
Can I use 12/2 wire for outlets in my electrical installation?
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.
What are the best practices for installing outdoor lighting wire to ensure safety and efficiency?
To install outdoor lighting wire safely and efficiently, follow these best practices: bury the wire at least 18 inches deep, use waterproof connectors, avoid overloading circuits, and follow manufacturer instructions. Regularly inspect and maintain the wiring to prevent hazards.
How do you determine the number of branch circuit for lighting load?
An engineered set of blueprints will have all of the pertinent information about circuit loading and circuit numbers and panel balancing already calculated. If there is no wiring schedule on the print then you refer to the electrical code book and abide by the regulations that are set out for circuit loading and the amount of devices that can be connected to that circuit. Single family dwelling: multiply the number of square feet by 3. So a 2500 sq ft home times 3 = 7500 watts. Divide that number by 1500 for #14 wire circuits or 2000 for #12 wire circuits. 7500 divided by 1500 = 5 #14 wire circuits or if divided by 2000 + 3.75 or 4 #12 wire circuits. This would be for the lighting load and general use receptacles through out the home. I always lay my circuits out where a circuit only covers 500 sq ft of the dwelling.
What wire should be used for outlets?
For outlets, it is recommended to use 12-gauge wire for 20-amp circuits and 14-gauge wire for 15-amp circuits.
