What is the capacity of 8 gauge wire?
The capacity of 8 gauge wire is typically around 40 amperes for general household electrical wiring. It could vary based on factors like insulation type, installation method, and specific application requirements. It's important to consult local electrical codes or a professional electrician to ensure proper usage.
450 watts divided by 120 volts equals 3.75 amps
450 watts divided by 12 volts equals 37.5 amps
watts divided by volts equals amps
Can 14-2 wire be used for outlets?
Yes, 14-2 wire can be used for outlets in residential settings. The 14-2 wire consists of a black (hot), white (neutral), and bare copper (ground) conductor. It is suitable for circuits with a 15-amp breaker and can safely power standard outlets.
You have three wires on the new switch but only two on the old?
The new switch is a 3 way switch which requires a common and 2 traveler's. The switch can be identified by no on off marks on toggle part on face of switch. Unless that third wire is a ground wire.
Can you use two 15 amp single pole breakers in place of a double pole 30 amp breaker?
Yes. An everyday occurrence of this circuitry is in your kitchen counter split receptacles. The top half of the receptacle is a 15 amp circuit and from the same breaker the bottom half of the receptacle is another 15 amp circuit. A two pole single handle breaker is a common trip. If one of the circuits fed from the breaker faults the other connected circuit will shut off also.
If you are talking about slot position in a breaker panel, you can remove the two pole breaker and install two single pole breakers.
How do you determine if an outlet is after or before the gfci?
GFCI receptacle has the ability to protect all receptacles down stream from the device. One way to see what is on the circuit after the GFCI is to trip (test) the device. Every thing that is connected downstream will shut off and there will be no voltage present to test. Any outlets ahead or upstream of the device on the same circuit will not be effected.

Trip the gici. If the outlet goes out it's after, if not, it's before.
In a commercial building What is the maximum amp load you can install in a 200 amp load center?
In a 200 amp load center, you should not exceed 80% of the panel's capacity to ensure safety and prevent overloading. Therefore, the maximum amp load you can install would be 160 amps. It's important to consult with a licensed electrician to determine the actual load requirements for the building.
It is not your problem. When you have finished the upgrade and called for inspection from theelectrical inspector, his paperwork is submitted to the utility company to allow a re connection of the service. Without the inspector's authorization the utility company will not connect to the new service. When all the paperwork is done and the utility company comes to connect it is their responsibility whether to use the existing drop or install a new one. It is the utility's responsibility to maintain their distribution system all the way up to the weather head on your mast.
Can a gfci outlet be controlled by a switch?
Usually not; you want your ground fault circuit interruption to be instantaneous and not removed from service by throwing a switch (who knows whether you will remember to put it back on line or not?).
<<>>
There is no reason that the GFCI can not be controlled by a switch but you have to keep in mind that every time you turn the receptacle off and back to the on position, you will have to reset the GFCI reset button which could become annoying.
How many amps equal 1 circuit?
80% of the rated circuit. 10 amp circuit is 8 amps, 20 amp circuit is 16 amps, etc.
You are talking of two different things here. The voltage rating of a wire is based on the insulation factor. Common wire voltages are 300, 600 and 1000 volts. Current rating of a wire is based on the diameter of the wire and measured in AWG. The electrical code states how much current can be legally applied to the wire. Answering your question, the 2 wire cable is probably 300 volt rated and your #14 size wire is rated at 15 amps. Code also states that conductors can only be loaded to 80% continuous load, so 15 x .8 = 12 amps.
How many watts will a 30 amp two pole breaker handle?
A two pole breaker clips to adjacent buss in the breaker panel, supplies 240 volt power to equipnent like clothes dryers and air conditoning.The breakers have a mechanical common trip so if either pole exceeds its current rating both lines are opened shutting down the equipment.Each pole can carry up to its rated current of 30 amps.Hope this helps.
How many amps will a number 2 copper wire hold?
Copper wires do not hold amps, they have a cross sectional area capacity to allow amperage to flow. In the electrical trade this is spoken of as "ampacity" of the wire. It is a combining of the two words amps and capacity.
A # 2 copper wire with an insulation factor of 60, 75 or 90 degrees C is consecutively rated at 100, 115 and 120 amps.
800 watt power coverter will produce how many amps?
To convert watts to amps, you can use the formula: Amps = Watts / Volts. Assuming a standard voltage of 120V, an 800-watt power converter would produce approximately 6.67 amps.
A garage door opener and the garage light can be on the same circuit. The garage door opener has to be up stream (non switched 120 volt source) from the light switch and the garage light.

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.

Is a 10 amp power tool better than a 5 amp?
A 10 amp power tool typically provides more power and better performance compared to a 5 amp tool. It can handle heavier loads and work more efficiently on demanding tasks. However, it may also be heavier and bulkier due to the larger motor required for higher amperage.
NO! I maintain an old school from the 1940's and i agree w/ the Indiana certified w/ electrical code of that day ( still applies as the copper has not changed) #10 is good for 20 amps up to 100' and then you must derated it to 18 amps for continuous load. # 12 good for 15 amps ( 12 amp continuous) The codes today are nuts but they do say " minimum" allowed by NEC. Ive been doing this for 30 years.
What wire goes to the rem on a amp?
The remote wire on an amp is usually connected to the remote turn-on lead from the head unit or a separate switched power source. This wire sends a signal to the amplifier to turn on or off based on when the head unit is powered on or off. It is typically colored blue on most wiring harnesses.
20 amp switch in a 15 amp circuit?
It can be done although it is bad practice provided the load doesn't continuously require more that 15 A. You should then use a 15 A fuse to protect the switch. Actually a fuse or circuit breaker is only there to protect the wiring and device and nothing else, e.g., if you run 14AWG wire then you want to protect that with a 15A (or smaller) fuse or breaker. Similarly 12AWG wire should be protected by a 20A (or smaller) fuse or breaker. The receptacles will only accept devices rated for them, i.e., NEMA 5-15R is rated at 125V 15A. NEMA 5-20R is rated at 125V 20A... the 5-20R is commonly known as "T" rated as it will accept either NEMA 5-15P or 5-20P plugs. The 5 indicates that it is a 125V rated 2-pole, 3-wire grounding receptacle.. the 15 or 20 is it's current rating.
What all can you use 6 3 wire for?
A 6/3 wire typically consists of three insulated conductors (hot, hot, neutral) and one uninsulated ground wire. It is commonly used for applications requiring 240 volts, such as appliances like stoves, dryers, and hot tubs, where both 120V and 240V services are needed. It is important to always consult local electrical codes and hire a licensed electrician for any wiring projects.
1200 watts is equal to how many amps?
To calculate amps, you need to know the voltage of the circuit. The formula to convert watts to amps is Amps = Watts / Volts. If the voltage is 120V, then 1200 watts would be equal to 10 amps (1200 watts / 120 volts = 10 amps).
5000 watts at 240 volt will draw how many amps?
To find amps if watts and volts are known, use the formula;
watts / volts = amps
or 5000 / 240 = 20.83 amps
Why do my 2 switches not work to my one set of connected hall ceiling lights?
I have trouble understanding your question. But I think you are saying that you have two switches that control one light and want to know why it is not working. More than likely is that you have two way switches instead of 3 way switches installed. 3 three switches cost a little more and are a little more difficult to install but if you recently replaced these switches you may have replaced them with the wrong type.
