Is it safe to cut through all the wires at the same time in a 14-2 romex wire while the main breaker is shut off?
If you're ABSOLUTELY CERTAIN that the breaker is off... no problem. Cut them all at once if you like.
However, just as many people have been shot with an "unloaded gun", many people have been electrocuted by a circuit that was shut off.
If you use lineman pliers that have an insulated handle, (don't touch the metal part) and the somehow the breaker DIDN'T get shut off, you'll be startled, the lineman pliers will be destroyed and there will be a puff of smoke to let you know that it was the"other" breaker.
As always, if you don't know exactly what you're doing, hire a professional.
Neither, the ground will be bare copper in lumex/romex or green when wired in single wires through pipe.
The key is that you don't want to cause over-heating in wire. The answer is you can probably do what you want unless it involves high current and a small cross section in wire mold such that the Romex could generate too much heat. You could always strip out the wires inside the Romex and just run them in the wire mold.
The wire is covered in a rubberized plastic and it called Romex
No, electrical wires can only be run in parallel on wire sizes 1/0 and larger. To supply a load of 30 amps you will need #10 wire and a 30 amp breaker.
You need no conduit on a residential home using Romex wiring with wooden studs. For a 15 amp circuit use 14/2 wire with a 15 amp breaker. This can only be used in bedrooms, living rooms, and dining areas. All other areas of the home require 12/2 wiring with a 20 amp breaker.
I believe it is, as long as the wires are the same size i.e. 2 12/2s or 2 14/2s.
Turn the main breaker off. Disconnect the two wires connected to the existing breaker. Remove that breaker and install the new one. Connect the 2 wires to the new breaker.
Romex plastic insulator or metal clamp type insulator.
Insulation is used to prevent contact with other metallic objects, such as other wires. This helps to prevent short circuits. Two common wires used in residences are Romex (NM-non-metallic) and BX (flexible metal covering). Romex is usually required in areas of high corrosion content, such as near bodies of water. If BX were to be used, it would quickly corrode and lose its protection. Romex has been around since 1922!
Hopefully just the black wires are on the breaker. Two circuits on one breaker. Shouldn't be a problem. It would depend on how many outlets or lights were on the breaker in total. Even then, there is very little chance of something drawing current from every outlet at the same time. The only thing is you can't put two wires under one breaker (by code). You would have to wire nut them with a pig-tail… Read More
Most household wiring is type NM cable, sometimes referred to as Romex.
If it was two wires under one screw on a single-pole breaker, that would not be proper, and most probably against electrical code. If it was two wires, each under their own screw on a double-pole breaker, then that would be a 220 volt circuit; each wire going to its own "leg" of the breaker panel.
Electric heat, heat rated insulation on wires, and instead of blk & whi colored wires under the pink sheath they are identified with a red & blk signaling that it's a 220v system.
Usually there are 3 wires. The Black wire or the "hot wire" this is connected to a circuit breaker or a fuse. The White wire returns the electricity from the load like a light bulb, motor, etc. to the electric panel. Technically it is a current carrying ground wire and you can get a shock from it especially from a ballast from a fluorescent light. The green or bare copper wire is the ground and… Read More
A small appliance circuit will be protected by a circuit breaker rated at 15 amps if the circuit wires are #14. If the circuit wires are #12 then a 20 amp circuit breaker could be used.
many wires are. such as 14-2 Romex. 12-2 Romex. Any THHN wire of any size. This list is very long. If you have a speific application then you need to check the NEC 2005 Table 310.13 Conductor Applications and Insulations.
Shut the main breaker off on your distribution panel. Remove the cover. Look at the colour of the wires that are connected to the breakers. If they are silver in colour then they are aluminum wires. If they are copper in colour then they are copper wires. Replace the panel cover and turn the main breaker back on.
It should be connected to circuit breaker. Circuit breaker will automatically discontinue the flow of electricity if it detects faulty condition.
Electrons flow through wires that are hooked to a battery. The battery's negative terminal repels the electrons, while the positive terminal attracts them.
Remove the breaker in main panel and either remove wires from main panel or cap off wires with wirenuts and label for possible future application. Put a breaker filler strip in hole left by missing breaker. At outlet you can just leave outlet or remove from wall and repair hole in wall. If you remove outlet and leave wires in wall it is best to totally remove wire from main panel.
If you have an electrical outlet not working and you have an idea what you are doing, you set out to repair it. First, you check the circuit breaker for a thrown circuit breaker. If that is not the case, you get a volt meter. When you have a volt meter, you throw the circuit breaker to that outlet. Then you take a screwdriver and you remove the outlet but keep the wires attached. You… Read More
A circuit breaker sets a limit on the amount of amperage that can be applied to the circuit's conductor. This is why wires and breakers have amperage ratings. The wires ampacity is matched to the breakers ampacity. If there is a higher that normal amperage capacity, than what the wire is rated for, the breaker will trip the circuit open.
Yes as long as they are in a romex style wire. Like 12-2 for example. Which is individual wires incased in an outer jacket. You should never have just single wires running in the attic unprotected or anywhere for that matter. Individual wires must be in a conduit. And any splices should be in a box.
install breaker in panel and put the hot wire on the breaker and also there should be a place for the neutral on the breaker also both wires will be landed on the breaker in different spots and then take the white wire that is coiled on breaker and land it on the neutral bar
My circuit breaker keeps popping I have replace the 2-prong outlet with a 4-outlets and why is it still popping?
A breaker trips when there is too much current. If you unplug everything on the circuit and the breaker still trips then you have a wiring problem or a bad breaker. From your description it is not possible to be certain if the problem started when you installed new outlet or previously. You have to describe your problem in better detail to get a good answer. When you have a circuit that trips the corresponding… Read More
Christmas light are causing the 15amp circuit breaker to trip and Circuit Panel is full Can I upgrade to a twin circuit breaker without installing a subpanel?
Your only hope is that someone wired the box not to code and that there are two wires going into the offending breaker. If you can't separate wires you can't distribute the load.
A circuit breaker is designed to 'break' in a circuit if a short circuit (or other malfunction) occurs. This prevents overheating (or burn-out) of the circuit wires. In older systems, you would need to find which fuse wire has fused and replace it. In a circuit breaker, once the fault has been found and corrected, the breaker is simply switched back on.
A breaker is a device that is used to connect and disconnect the buss bars of an electrical panel to the feed end of wires that feed an electrical load. The function of a breaker is to protect the wires from an overload by the use of an internal thermal trip, and to protect the load and wires from a short circuit by use of an internal magnetic trip.
A circuit breaker ensures that a circuit cannot draw more amps that are rated for the breaker. It protects the circuit wires from overheating and arcing so that a fire or shock hazard does not result.
Overcurrent current protection is for the wires
Depending on how the two wires are connected in the circuit ,one scenario is the breaker to that circuit will trip.
Code only allows one wire to be connected to a single pole breaker. Any additional circuitry has to be done in a junction box downstream from the breaker.
The key is the protection of the wires. If you are using single wires you will need a conduit of some sort. Don't just run the single wires in the wall. Multi wire Romex or metallic shielded cable are used to provided added protection to the encased conductors.
Insulation can be put over wires to prevent short circuit breaker trips.
The only way to ground your system if you're using plastic boxes is to continue the chain by connecting your ground wires together--just as you would with the hot and nuetral wires--through the entire circuit all the way back to the whole house gound in the circuit breaker panel.
The purpose of a circuit breaker is to open the circuit in the event of an overload. Wires/conductors are only rated for a specific Amperage. If this amperage is exceeded the conductor/wire begins to heat up and given enough time it becomes a fire hazard. For instance a 15 amp breaker will trip once the Amps drawn through that circuit exceed 15 amps. The short answer is to keep you safe.
#12 AWG Copper. (The previous answer, "12/2 with ground", was incorrect. That answer specifies Romex. Not all homes are wired in Romex, and if they were, it would be acceptable to use any number of conductors inside the cable, including 12/2, 12/3, 12/4, and even the "new" 12/2/2.) If you receive free breakers with a "panel kit", and they are 20A breakers, keep in mind you cannot use them where a 15A breaker was previously… Read More
How do I wire a 220v ballast when it has only 1 wire labeled 220 when I have 2 wires coming off of my double leg breaker?
Your ballast should show two wires for supply side of ballast. Make sure that neither side of this is grounded to the light and connect the 220 V from your breaker to these two wires and then connect a ground to the chassis of the light from the panel.
to wire a 3-way like this you first need to run 14/3 romex wire from the light box to each of the 2 switch locations. at each switch connect wires as follows: white wire to common screw(usually black or brass) connect red and black wire to silver colored screws, does not matter which way. in the light box you need to identify you incoming power, once you have identified that wire connect one of the… Read More
The 20A breaker can handle (25%) more power than the 15A breaker, because of this the wires used inside the walls is larger. Some circuits must be 20A, the laundry and kitchen are examples of 20A circuits.
What would be the cause and solution of partial electricity going out if wires may have touched when fixing a closet switch?
Blown fuse or tripped breaker. Replace the fuse or reset the breaker.
No the service wires need to be upgrade to 3/0 copper or 250 mcm aluminum. This will require a power company to disconnect so you can upgrade the service. These wires are always hot unless the power company disconnects from their source. Do it right pull a permit and upgrade Additional information: Some meter base boxes include a shutoff/breaker. If you are only looking for additional space inside the breaker panel, and do not upgrade… Read More
wires circuit breaker switches resistance
There is no path for current to flow from the wires to the ground, through the bird. It is possible that touching two wires could cause current to flow, but the individual wires are usually far apart.
If the load is single phase and the load requires 460 volts to operate, then two conductors will be needed and they will connect to a two pole breaker. If the load is three phase and the load requires 460 volts to operate, then three conductors will be needed and they will connected to a three pole breaker. The sizing of the wires will depend upon the current that is drawn by the loads.
A 40 amp breaker is used in conjunction with AWG # 8 copper wire. The black and red wires are connected to the breaker. The ground wire is connected to the ground bar and the white wire is connected to the neutral bar.
Why would a breaker trip after 30 sec with nothing plugged in to the circuit except the tv that is turned off?
First unplug the TV. Some TVs may still draw current when off, but not enough to cause a breaker to trip. However you still want to make sure you don't fry your TV as you troubleshoot. If there is nothing plugged in to any outlet on the branch circuit and there are no light fixtures the problem is a bad breaker or in the wiring. The ideal is to have an electrician troubleshoot since you… Read More
circuit breakers are designed to cut off power to an electrical circuit when too much amperage is drawn through the wires. different size wires are used to carry more or less amperage. for instance, 14 guage wires are usually set with 15 amp breakers. and 12 guage wires are usually set with 20 amp breakers. pulling too much power through too small of wire will cause the electricity that is supposed to be going to… Read More
A GFCI outlet or breaker is designed to measure the current flow on both the hot and neutral wires connected to it. A "trip"will occur whenever the is a 5mA(millamp) difference between the two currents. Examples would be when you drop a hairdryer into water allowing power to flow through the water and not through the wires correctly. This system is designed as a life safety system to stop power from flowing through a person… Read More
