New Electrical Work

With a 15 A breaker you need 14 Gauge wire. Normally you would only put 8 outlets on a 15 A circuit. If you have the option you shoudl consider a 20 A circuit, use 20A receptacles and 12 gauge wire.

Comment:

The question was on a homeowners electrical exam. My answer was also 14 gauge however, the tester said the answer was 12 ga. I thought maybe there was something special about the 10 outlets. For example, 10x180 VA per outlet/120V = 15 A which is right at the limit for 14 ga but would be 75% for the 12 ga wire.

A red wire switch leg is a specific wire used in electrical wiring to connect a switch to a light fixture or another electrical device. The red wire serves as the hot wire that carries electricity to the switch, allowing it to control the flow of electricity to the connected device. It is essential to follow proper electrical codes and guidelines when working with red wire switch legs to ensure safety and proper functionality.

depending on the insulation type. Most 12 AWG wire will carry that current capacity either. Unless you are running it in the desert or some place extremely hot where derating becomes a factor.

Depends on the supply voltage. For UK 230 Volts, 1800 Watts would mean the current drawn was 7.83 Amps.

Watts=Volts x Amps, so Watts divided by Volts gives the current in amps.

It depends on the current flowing in the wire. V=IR. The wires have resistance (easily calculated, approx. .32 ohms for 200 feet of wire (100 feet out and back)). If 20 amps are flowing in the circuit the the voltage drop is about 6.4 volts. That means you're converting electricity to heat in the wires at a rate of about 130 Watts. If less current is flowing then there is a smaller voltage drop in the wire.

A double pole breaker has one pole attached to one side of your breaker panel's bus or hot leg, and another pole attached to another hot leg or bus, if it is in a residential panel (in the US) each leg of the breaker is 120 volts to ground or neutral and 240 hot leg to hot leg. The 15 amp indicates that the breaker will trip if the circuit exceeds 15 amps across the two outputs of the breaker.

For a 100 amp sub panel located 300 feet away, you should use 3 AWG copper conductors. This will help minimize voltage drop over the distance, ensuring the sub panel receives the required amperage reliably. Be sure to consult local electrical codes and regulations for specific requirements in your area.

Yes you can as long as it is feed off of a 20 amp circuit in at least #12 gauge wire.

The white wire is typically neutral, the black wire is usually hot or live, the red wire may be a secondary live wire or used for a separate function, and the bare wire is typically the ground wire for safety purposes in an electrical circuit.

Sort of confusing are you using 14-3 just for the receptacle with 14-2 to the breaker or the other way around. Either way doesn't matter since you only need 2 wires and a ground for the outlets. The 14-3 should have Red, Black, White and bare wires. 14-2 should have Black, White and bare. All you need are Black, White and Bare. Forget about the red one. Hook the two outlets together with short jumper wires about 6 inches long. Looking at the outlet with the ground facing down, the bare wire goes on the bottom green terminal. The white wire goes on the left side of the outlet. The black goes on the right side of the outlet. Take the 6 inch jumper wire and go from the left side of one outlet to the left side of the second outlet. White to white, black to black, bare to bare. Connect the wires coming from the breaker to the other terminals on one of the outlets. Power comes in to one outlet and then to the second. If the wires are capped in the breaker box, you only need to connect the Black White and bare ones. Do this with the power off.

i would have to take a guess at this one and say yes aslong as its rather tough to snap. if i remember right 26 gauge wire is rather thin. I use 20 gauge wire 0.8mm and finding it a little to thick for anything smaller than a fox but 24 gauge is the lowest i would probably go.

ive been taught though that the thinner the wire the better as long as it can take the strain. The U.S and British army both carry 24 gauge wire in their survival kits for multiple purposes, snaring being one of them.

A fault current on a twenty amp branch circuit can cause the main breaker to trip due to the higher-than-normal flow of electricity, which exceeds the circuit's capacity. This could be caused by a short circuit (abnormal connection between conductors) or a ground fault (unintended connection between a conductor and ground). The main breaker detects this overload and trips to prevent overheating and potential fire hazards.

No. The breaker must protect the circuit components such as wiring, outlets and switches that are connected to the breaker. Therefore if you have a 30 amp circuit as dictated by its components you need to protect it with a 30 amp or less breaker.

The minimum outlet box depth that can be used in old work installations is typically 1 1/2 inches. This depth allows enough space for wire connections and devices to fit securely inside the box without overcrowding. It is important to ensure that the box depth meets local electrical code requirements.

The amps drawn by a 65 watt light bulb should be 65/120 or 0.54167. This fraction of an ampere may be restated as 541.67 milli-amps.

To determine the hours a 3600-watt load will last on a 637 amp battery, you need to convert the wattage to amperes. You can do this by dividing the wattage by the voltage of the battery. Assuming a standard 12-volt battery, 3600 watts divided by 12 volts equals a current of 300 amps. Dividing the battery capacity (637 amp-hours) by the current (300 amps) gives you approximately 2.12 hours of runtime.

I can think of exactly one justification for 400 amps residential service: a tankless electric water heater, which pulls 150 amps all by itself. In general, if you want 400a service in a home you have to justify it to the electric company--they want to be sure you aren't planning to take up smelting aluminum as your new hobby.

If you're going that way, most guys install two 200a load centers with a Siemens 400a meter base. The Siemens meter base has a 400a main breaker in it.

A 30 amp breaker is designed to trip at an earlier point than a larger 40 amp breaker so one appliance that operates on lower amperage level could be unsafe or damaged before it could trip the higher 40 amp breaker. Also, the existing wiring may not be rated for 40 amp service.

A 65 Watt incandescent light bulb should draw 65W/120V = 541.67mA

Find out your supply voltage, and divide 65 by it:

I(amps) = P(watts)/V(volts)

= 65/V

If you are talking a pure electric you are range limited; you must live where you can install a charging station; the car will be advertised as nonpolluting, but that ignores how the electricity is produced to charge the battery; the car is likely more costly, but subsidized by the government; it is quiet, but some think this makes it more dangerous; it may be cheaper to operate but may require 10 years to realize a savings given inflated up front costs. There are various options to extend the range of the electric, but none are really good alternatives given current technology. People are not buying electric vehicles in large quantities, so likely the disadvantages outweigh the advantages for most people. It is reported that the medium family income for a Chevy Volt buyer is $175,000 annually. Hence, it certainly isn't the technology for the common person.

This is one of those cases where if you don't know, you shouldn't do it.

The house doesn't have the drywall up yet, correct?


I would call an electrician. The guy will come out and tell you what to buy. You buy it and bring it home. He brings his helper and installs it. I've seen some electricians who'll show you how to pull the wire yourself--this is the part that is easy. You pull the wire, and he hooks it up for you. Other electricians want to do it all themselves.

In order to calculate wattage, you must know the value of the voltage source.

Using Ohms law, you can calculate wattage by multiplying the number of volts by the number of ampers (P=I X E), where P is the power in watts, I is the current in Amperes, and E is the source voltage in Volts.

So, at 240 volts, 100 amperes would represent 240V X 100A = 24,000 watts.

At 120 volts, 100 amperes would represent 120V X 100A = 12,000 watts.

At 12 volts, 100 amperes would represent 12V X 100A = 1200 watts.

Note: This is only completely true for DC (Direct Current) or 100% resistive AC loads. If you're calculating wattage on an inductive load (such as a large tranformer or fluorescent light fixture), for any given amount of current, the actual value for wattage will always be less than that calculated amount.

If you're unsure about the nature of an AC load, you can only use ohm's law as an approximation of wattage. For AC loads, you will often see the term "Volt-Amperes" used instead of "Watts" when calculating the power consumption of AC loads.

The light selected for a clothes or coat closet needs to provide adequate brightness and color rendition of the items -- including ties, hand bags, and belts. I think halogen lighting will allow you to see bright, true colors in a closet.
