What else can I help you with?
Where would a 100 amp breaker be used?
In a residential application it would most likely be used as the breaker for the entire main electric panel or a subpanel feed.
How should the feeder wires to a subpanel from the main panel ideally be protected?
Sub panel feeder wires are run just the same as any of the circuit wiring in the house. The sub panel is just another load circuit. Make sure that the correct wire sizing is done to feed the sub panel. It can be run behind wall board. If run on the bottom of the floor joists it is best to nail a board to the underside of the joists and then staple or strap the cable to it. If it is below the five foot level from floor grade and on the surface it must be mechanically protected until it rises above the five foot level.
Can you tap meter and feed panel in detached garage?
No. Any connections to the detached garage have to be after the main disconnect of your house panel. You have two options here. You can replace meter with a meter disconnect combo and have the main feed your house and add a breaker to feed the garage or You could install a 400 ap service and place two disconnects at the meter. one for the house and one for the garage. unless you are going to have a serious electrial load in the garage you sould just feed off the panel in the house for cost effectiveness.
Is a 15 amp 2 wire outlet wired with copper wire?
Yes it is wired with copper 2 wire is also known as 14/2 wire is use for switches,outlets,lights. and a 15a outlet should only be on a 15a breaker the main power feed to your meter to your panel is aluminum and can take more of a load than copper. In the US, 15 amp receptacles can be installed on 20 amp circuits if there is more than one receptacle on that circuit. Copper wire can carry a larger load than aluminum wire of the same size.
Can you feed a 208v 200amp panel from 480v 20amp circuit?
Not directly, you would need to transform 480v circuit to 120v with a transformer first.
Where would a 100 amp breaker be used?
In a residential application it would most likely be used as the breaker for the entire main electric panel or a subpanel feed.
I have a Transformer 480 primary 208 secondary feeding 1 200amp mb 42 space panel I need to feed a subpanel 6 ft away I'm thinkin feed through lug at top of bus or at feed through MB suggestions?
The sub-panel need to be fed from the main panel, by way of a circuit breaker connected to one of the breaker locations. Or if your sub-panel has a main breaker installed you can feed from the main panel with a sub-feed lug kit. This looks like a breaker, but is only a point where you can branch off the sub panel.
Can you use a 200 amp subpanel on a 100 amp branch circuit?
No, it is not recommended to use a 200 amp subpanel on a 100 amp branch circuit. The subpanel rating should not exceed the capacity of the branch circuit to prevent overloading and potential safety hazards. It is important to match the subpanel rating with the branch circuit capacity to ensure proper electrical function.
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.
Can you use aluminum service cable to feed a sub panel?
Yes, as long as it has the necessary ampacity for the load and is properly fastened at each terminal. For example, we have a 4/0 aluminum cable feeding our 200 A subpanel 120 feet away.
Why does your solar hot water system not get hot?
The solar panel pumps are not working,then may be solar panel copper tubes block,may be water not store in feed water tank.
Can a 60 amp main breaker be used to supply a 100 amp subpanel power so that I can take advantage of the extra curcits provided by the larger panel I'll only be using 45 amp at any time?
You can certainly use the larger breaker panel provided that you sub-feed the panel using breakers that do not exceed the rating of any down-stream device. If you have any concerns or do not thoroughly understand what you are doing, contact a qualified electrical contractor in your area.
Can you use 10 2 wire to come off a 60A double throw and run it to a sub panel with 2 spaces 20A each and be up to residential code?
No, using 10-2 wire for a 60A circuit is not up to code. For a 60A circuit, you need to use at least 6 AWG copper or 4 AWG aluminum wire. Also, the subpanel should be sized appropriately for the amperage of the circuit it is fed from. In this case, the subpanel should be at least 60A, not 20A.
What size wire is needed to feed a 125 amp sub panel from a 200 amp panel less than 200 wire feet away?
For a 125 amp sub panel located less than 200 feet away from a 200 amp panel, you would typically use a 2 AWG copper wire or 1/0 AWG aluminum wire to safely carry the current load. It's important to follow local electrical codes and regulations when selecting the wire size.
How does the feed through panel function in the electrical system?
The feed through panel in an electrical system allows for the connection of multiple circuits by passing power through the panel without the need for individual connections.
Should a 2 AWG copper wire be used to feed a 125 amp sub panel located 125 feet from main panel?
No, the conductor is too small. The feeder to a 120/240 volt sub panel should be a 1/0 copper or a 2/0 aluminium conductor. This size conductor will limit the voltage drop to 3% or less when supplying 125 amps for 125 feet on a 240 volt system. ACWU 90 (Armoured Cable Wet location Underground 90 degree C). ACWU 90 cable is code approved for direct burial and is used in many projects as an underground service distribution feeder. Aluminium is much cheaper than copper for this type of installation.
How should the feeder wires to a subpanel from the main panel ideally be protected?
Sub panel feeder wires are run just the same as any of the circuit wiring in the house. The sub panel is just another load circuit. Make sure that the correct wire sizing is done to feed the sub panel. It can be run behind wall board.
