What else can I help you with?
What wire size do you need for a 125 amp panel with a 100 amp main breaker?
A #3 copper conductor with an insulation factor of 90 degrees C is rated at 115 amps. Even though the panel is rated at a higher amperage it is the main breaker that governs the wire size.
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.
What size Aluminum wire is used for ground in breaker box?
For a 100 Amp breaker panel it would be 2 AWG. For 150 Amps it would require 2/0 (2 ought) aluminum wire.
What size breaker is needed to supply a sub panel that is feeding a range and dryer?
If there is a possibility of both operating simultaneously, then a 100 amp breaker (actually 80 amp if you can find one), and appropriate wiring would be required. Even if they were not expected to operate simultaneously, it would be prudent to wire as if they were.
Can you put a 60amp breaker and a 50amp breaker on a 60amp subpanel just as long as they are not being used at the same time?
You can. Using these size breakers in a 60 amp sub panel might be pushing the limit for breaking the sub panels feeder breaker. The breaker feeding the sub panel will have to be no bigger than 60 amps because of the main bus bar capacity of the sub panel. It would be better to install a 100 amp sub panel and then there would be a bit of a buffer and you will have the ability to add additional small load circuits.
What is the maximum amperage capacity of a 100 amp panel with main breaker?
The maximum amperage capacity of a 100 amp panel with a main breaker is 100 amps.
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 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.
What is the maximum amperage capacity of the main breaker in the electrical panel, specifically looking for a 100 amp main breaker?
The maximum amperage capacity of a 100 amp main breaker in an electrical panel is 100 amps.
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.
How do you tell the difference between 100 amp and a 200 amp box?
You can typically determine the amperage of an electrical panel by looking at the main breaker. A 100 amp panel will have a main breaker rated at 100 amps, while a 200 amp panel will have a main breaker rated at 200 amps. Additionally, the size and number of circuit breaker slots can also be indicators of the amperage rating.
Can a 100 amp main have 2 50 amp breakers?
Yes, a 100 amp main panel can have 2 separate 50 amp circuits protected by 50 amp breakers. This configuration allows for two separate circuits drawing up to 50 amps each from the main panel without overloading the panel's 100 amp capacity.
What wire size do you need for a 125 amp panel with a 100 amp main breaker?
A #3 copper conductor with an insulation factor of 90 degrees C is rated at 115 amps. Even though the panel is rated at a higher amperage it is the main breaker that governs the wire size.
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.
What is the compatibility of the Pushmatic 100 amp breaker with the electrical panel in my home?
The compatibility of a Pushmatic 100 amp breaker with your home's electrical panel depends on the specific model and specifications of both the breaker and the panel. It is recommended to consult with a licensed electrician to ensure proper compatibility and safe installation.
What is the recommended wire size for a 100 amp breaker?
The recommended wire size for a 100 amp breaker is typically 2-gauge copper wire or 1/0-gauge aluminum wire.
Is a 12 gauge wire on 20 amp breaker safe for a sub panel?
No, a 12 gauge wire is rated for 20 amps, which matches the breaker size. It is not recommended to use a wire that matches the breaker size as it can result in overheating and potentially cause a fire hazard. Consider using a thicker wire, such as 10 gauge, for the 20 amp breaker to ensure safety for the sub panel.
