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.
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.
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.
Can you use a 200 amp subpanel on a 100 amp branch circuit?
Yes you can, but it is all about distribution of the load. You still have a maximum limiting current of 150 Amps. So if you did use 100 amps on the sub-panel that would only leave 50 amps on the main. Since power usage is usually not constant and varies by day and situation, you just need to make sure the load is distributed so you don't start tripping breakers.
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 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.
How do you read breaker box amps?
The main breaker will have marking indicating size of electrical service, or if it is a fuse system....the fuses will have current ratings. If it is a subpanel, it might not have a main breaker. In this case you would have to look in the panel that the feed is coming from and find the size of the breaker that is feeding it. In either case you must look for the manufacturer's label that will have the maximum current the panel can handle, make sure the breaker feeding the panel doesn't exceed this rating.
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.
What size wire is needed to feed a 125 amp sub panel from a 200 amp panel less than 200 wire feet away?
A #1 copper wire with an insulation rating of 90 degrees C is rated at 140 amps.
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. 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.

Can you feed a 60 amp sub panel from another 60 amp sub panel?
Yes
