Can a circuit breaker with a breaker lock out installed be used as the disconnecting means hot a 240 volt 30 amp hot water heater in a single family dwelling?
Answer for USA, Canada and countries running a 60 Hz supply service.No.A disconnecting means must be1. Within 50 feet.2. Within sight of.3. Readily accessible.A breaker with a breaker lock out installed is simply not readily accessible.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.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
Can a double pole 20 amp breaker be used with 12-2 wire for a single 220 circuit?
The term "double pole" usually means a breaker with 2 handles that attaches in the space as a normal single pole breaker. If this is what you mean, no, you cannot. There is no potential, or voltage, between the wire terminals. If by "double pole" you mean what is usually called a 2-pole breaker, which is a breaker with 2 handles that attaches in the space of 2 single pole breakers, then yes, you can use this breaker and 12/2 wire to produce a 220v circuit.
20 amp breaker power verse 15amp breaker power?
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.
Can you run an additional breaker panel parallel to the existing one?
It is not in parallel. You put a breaker in existing panel and use that to feed the subpanel. The Amperage of this subfeed breaker should match the rating of the new panel. For example a 100A breaker might be typical. Remember that ground and neutral are only "bonded" at the main panel. Usually a subpanel has a means to separate the neutral and ground in a subpanel. Be careful since everything about doing this is dangerous.Another AnswerYes, you can have two breaker panels in parallel. If you had a 100 amp panel on a 200 amp service (or increase the size of the service, check with your power company on the size of your service, you could add a second 100 amp panel in parallel with the first. You can have up to 6 disconnects per service, but they must be located adjacent to each other or in the same enclosure. So either install the second panel beside the first or a 100 amp disconnect beside the first panel and feed out of the disconnect to the new panel located where you need it.
What are two places that neutral buss bar in the service panel can be grounded?
Answer for USA, Canada and countries running a 60 Hertz supply service.There is only one place that the neutral can be grounded and that is at the service distribution box that containing the first over current device. You have the neutral coming into the box and the ground wire going to either a grounding rod or the water line where it comes into the house.

Can you move electric breaker box?
Answer for USA, Canada and countries running a 60 Hz supply service.Yes. The NEC requires that your service disconnecting means be as close as practical to where the service conductors enter a building. In a home, your service disconnecting means is the main breaker in the panel.If you choose to move your panel away from the closest practical location, you must install a separate disconnecting means and make your grounding conductor, grounded conductor (neutral), and grounding electrode conductor (conductor to your ground rods) bonds within that enclosure. You must then isolate your grounding conductor and grounded conductor (neutral) everywhere else. This is where the confusion arises because in homes we are used to sharing the same set of terminals for the ground wires and neutrals.In this type of installation you must have a ground bar which is bonded to (usually just connected to) the panel enclosure for your ground wires and a separate set of terminals for your neutrals that is isolated (insulated) from the panel enclosure.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.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
What do you mean by acb and vcb?
acb means AIR CIRCUIT BREAKER ,& vcb means VACUUM CIRCUIT BREAKER
Why you switch off circuit breakers before operate disconnecting switch at substation?
It probably doesn't matter. But a "disconnecting means", as the NEC calls it, is not intended to be operated while under load, which is when the equipment is running. It is intended to isolate the equipment so it can be serviced safely. A breaker by its very nature is intended to be operated under load. The larger the equipment, the more this matters.
What does writ returned mean?
It means the court that issued the writ requires that it be served and the results of the service retunred to the court.
What do electricians sometimes refer to as "disconnects" or "disconnecting means"?
Electricians sometimes refer to disconnects or disconnecting means as devices that are used to disconnect electrical power from a circuit or equipment for safety or maintenance purposes.
What do electricians sometimes refer to as "disconnects" or a "disconnecting means"?
Electricians sometimes refer to disconnects or a disconnecting means as devices that are used to completely shut off the power supply to a circuit or equipment for safety purposes.
Why would power be received before breaker but with breaker on no power is in any recepticles?
The voltage before the breaker is from the distribution panel's buss bars. This voltage is controlled by the panel's main breaker. To have no voltage on the terminal of the breaker means that either the breaker is shut off or it has gone into a trip position. If it has tripped push the handle of the breaker to the off position and then to the on position. This should reset the breaker. If the voltage is not present at the output terminal of the breaker after resetting it, then replace the breaker as it has a fault in it.
What did warlock mean in old English?
It means Traitor or oath breaker
What is the LBB protection?
Lbb means local breaker backup protection
What is the margin of safety with selecting circuit breakers?
The NEC requires that if the intended rating of a circuit corresponds to a standard size breaker then that size breaker must be used. In most instances, "rating of a circuit" means the intended connected load plus 25%. If the intended rating of a circuit does not correspond to a standard size breaker, you can go up to the next standard size without any other adjustments. In most circumstances, besides what I've already stated, a 14 gauge copper wire cannot be connected to a breaker larger than 15 amps, 12 gauge copper to a 20 amp breaker, and 10 gauge copper to a 30 amp breaker.
High voltage will trip a circuit breaker?
A higher voltage means that a higher current will flow in the same load. It is the current that causes the breaker to trip.
