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.
How do you replace a 15 amp breaker in the circuit box?
The breaker will have a black wire connected to it. Turn off the main breaker and then disconnect that black wire from the breaker. The breaker will snap into the main bar. Remove the breaker and install the new one. Reconnect the black wire to the breaker and then install the cover and turn the main breaker back on.
Can you install a 2 20 breaker into a breaker box that has space but all other breakers add up to more amps than the 200 amp main breaker?
No, you cannot install a 2x20 amp breaker if the total amperage of all the breakers exceeds the main breaker rating, as this would overload the system. The total amperage of the breakers should not exceed the main breaker rating to ensure safe operation of the electrical system.
How do you find out how big your main breaker box is?
Simple. Your main electrical panel will have a "main breaker". This will be a two pole breaker, usually at the top of the panel. It will have a number on the breaker "handle" such as 150 or 200. This is the maximum number of amps your panel can supply. Most newer homes, 1975 and newer have a 200 amp service.
What can a loosely connected electrical wire in a breaker panel cause?
A short, which will trip the main breaker.

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.
What is the purpose of main switches?
The main breaker limits the overall current to the building. Most buildings have many branch circuits that sum to more current than the service is rated for. This is not a problem as all the branch circuits are not used under high current draws at the same time. The main breaker protects the main wiring in the meter and to the transformer, and the transformer itself, from heavy current loads. It also protects from shorts in the main distribution panel.
Is main breaker only powering one half of hot bus because when dryer is on some light on circuits on dead bus work?
Yes, it would appear that one side of the main is open at the fuse, breaker, drop conductors, or transformer.
Does the secondary feeder of a transformer need to be rated at less than the main breaker of the feeder supply panel?
It depends on the situation and how you are utilizing the transformer. Under certain conditions the secondary does not need to be protected. The protection on the primary is enough to protect the secondary side of the transformer.
What is the maximum amperage capacity of the main breaker in a 100 amp sub panel with main breaker?
The maximum amperage capacity of the main breaker in a 100 amp sub panel with a main breaker is 100 amps.
What precautions to be taken when working with Transformer?
Frist putt of the main incomer HT side then Rack out the breaker and put the LOTO after that Discharge the cable Both side (HT/LT).
What is the recommended size for the main breaker in a residential electrical panel, specifically for a 125 amp main breaker?
The recommended size for a main breaker in a residential electrical panel with a 125 amp main breaker is typically 150 amps.
What is different between feeder breaker and motor breaker?
You have to be careful with terms in the electrical field, Example: Main Feeder Circuits will feed a Transformer for distribution and each of those main circuits might feed numbeous Motor control centers. However each of those circuits could be called a main feeder for the motor control center. Confusing. We have High Voltage Transmittion tansformered down for Distribution. So normally a Feeder Breaker will feed Main circuits that will be used for distribution. Example Your home panel will have a main feeder circuit to the whole panel and distribution breakers to you home.
What are precautions to be taken at the time of back charging of generator transformer?
Nothing. If your system can run your house while the main breaker to the power grid is off, then back charging will occur as a byproduct while the main breaker to the power grid is on and you are using less power than you are generating. During times of a power outage, you'll want to cut the main breaker to the power grid, so that your system doesn't try to power the entire neighbor hood.
What is the usage of transformer?
The usage of transformer is to produce electricity from a main electric unit
