When buying a distribution panel look for the capacity rating of the bus. There are some panels that have a 100% rating and others that only have an 80% rating. This rating is reflected in the price of the panel. The least expensive panel might not be the right one for your application.

What is the largest sub panel you can install off from a 60 amp main panel fed by 100 amp service?
You can install a 100 amp sub panel off a 60 amp main panel fed by 100 amp service. This allows for the sub panel to be adequately powered with headroom for future circuits or expansions. It is important to ensure the wire size from the main panel to the sub panel is sufficient to handle the load.
What should an electrical panel rating be?
Depends on the load. Most residential homes require at the very least a 200 amp service panel.
What would happen if a 200 amp breaker is used in a 100 amp sub panel?
There are two things to think about here. First of all a 200 amp breaker will not physically fit into a 100 amp panel. This is so designed because the panel buss is not designed to conduct 200 amps before the current is cut off. A 100 amp rating on the panel is the maximum amount of current that the manufacturer states, that can be handled safely. Second if the 200 amp breaker is in the main panel then everything downstream from that breaker has to be rated for 200 amp conductivity. The wire size will have to be 3/0 from the breaker to the first over current device in the sub panel which will be the sub panel's main breaker. The sub panel can not be a load center but will have to be a combination panel. I doubt that the 100 amp sub panel's main breaker lugs would be large enough to connect the 3/0 cable.
How many amps does a 100 amp service supply?
A 100 amp service will supply your electrical current needs UP TO 100 amps.When doing load calculations on a 100 amp panel it can only be loaded up to 80 amps.
How many 50 amp outlets can you run off a 125 amp main panel?
It depends on the total amperage of the other circuits in the panel and the load requirements of the 50 amp outlets. As a general rule, it is recommended not to load a panel beyond 80% of its capacity, so in this case, you may be able to run one or two 50 amp outlets off a 125 amp main panel. It is best to consult with a licensed electrician to evaluate the specific situation and ensure it meets electrical code requirements.

Can you use a 100 amp sub panel with a 100 amp main?
Yes as long as the combined current from both doesn't exceed the limit of the main.
Is it OK to have 250 A of breakers in a 100 A panel?
Yes. Many installations have breaker totals higher that the main breaker of the panel. It is worked on a percentage basis. Not all of the breakers will be on at the same time. In a home, on a 100 amp panel the average load is 50 - 60 amps. The 100 amp main breaker is protecting the 100 amp rated panel board. If the load current goes higher that the panel board is rated at, the main breaker will trip to protect the board.

How many amps can be put on a 125 amp service?
You should not load a 125 amp panel any more than 100 amps.
What size breaker do you use for a 100 amp sub panel?
A 100-A sub-panel would be fed from a 100-A breaker.

Do you have to upgrade 60 amp service to 100 amp if you have a 30 amp HVAC unit installed?
Without knowing the sq. ft. area of your house and what appliances you have connected and if your hot water tank is electric it is hard to make an assessment. The average household draws about 50 amps so if you are adding another 30 you will be getting close to the limit of the new panel. Ask for an estimate on the 100 amp panel and then on a 200 amp panel. The labor costs should not be much higher for the larger installation of a 200 amp panel just the materials.

Can 100 amp distribution panel feed a 70 amp sub panel?
Yes they can. As long as the total load of all subs does not exceed the rated capacity of the main breakers, you should be fine, including 80 percent de-rating of any constant loads.
How do you wire a garage sub panel box from a 100 amp breaker in the house main panel?
you propaly can't sub panel from 100 amp panel. Just not enough amperage to be worth while. i had to up grade t a 200 amp main first and then I was able to take a 60 sub panel from that.
How many 50 amp outlets can you run off a 125 amp main panel?
It depends on the total amperage of the other circuits in the panel and the load requirements of the 50 amp outlets. As a general rule, it is recommended not to load a panel beyond 80% of its capacity, so in this case, you may be able to run one or two 50 amp outlets off a 125 amp main panel.
