However, their size makes them very stiff. You can’t ignore the fact that 1AWG and 2/0AWG wires are incredibly thick. You can use a slightly smaller wire depending on the temperature rating, distance, and material. You can run a 125A service on 1AWG copper wiring. But what about 125A? Do you have to increase the wire size? Not really. You need 1AWG wire to accommodate a 100A service. The difference between a 100A breaker and a 125A panel is too small to affect the operations of your appliance. In the case of 125A panels, 100A breakers are perfectly fine.Īlso, you don’t have to supply 125 amps to a 125A panel. Therefore, selecting the right breaker size is crucial. However, the solution is not a larger breaker because it won’t respond quickly enough to protect the wires. The breaker will trip if you exceed that threshold, cutting the power off and saving the wires.Ī small breaker is a nuisance because it will trip before your appliances acquire the power they need to operate. It will only permit a specific volume of electricity to pass through the wires. In fact, you can force as much electricity through a conductor as you want. However, a wire cannot control the volume of electricity it carries. The conductors should be large enough to transmit the current without overheating. Most people understand the importance of selecting the correct wire size. The breaker matters because it protects the wires. 100A Breaker Sizeġ00A breaker can work on a 125A panel. The only significant concern is the breaker and wire size: 1). What Is Required For A 125-Amp Service?ġ25A services have the same requirements as those of any other service. If you use ordinary household appliances and devices, they will probably tell you that 200A panels are adequate.

If you ask your local contractor to upgrade the panel to a 400A service, they may ask you to evaluate your electrical demands to determine whether or not the amp service is necessary. You only find 400A services in homes with items like hot tubs that consume immense volumes of electricity.

You are free to raise the capacity to 400 amps.īut the average house doesn’t require that much power. You can run all the heating and cooling systems you want without overloading your electrical service. A 150A panel counts as a large capacity electrical service. If you have the option, you should upgrade to 125, 150, or even 200 amps. You are more likely to find this capacity in older and smaller, the kind that don’t rely on high-end heavy-duty kitchen and laundry appliances, not to mention powerful air conditioners.ġ00A services are medium-capacity. It gives consumers enough electricity to run all the essential items. This is the minimum amp capacity the NEC expects to see. If you live in a contemporary house of 1,200 feet or more, 100-amp panels are the starting point. But 30 and 60A services are far too small to serve the needs of a modern home.

By the 1960s, many places had jumped to 60-amp panels. For instance, you had houses in the first half of the 20 th Century with 30-amp panels. The size matters because it affects the devices you can run on that electrical service.Įlectrical services were so much smaller in the past. You have to select the electrical service carefully. If you check the panel, it will tell you the total capacity of the electrical service. But if two bus bars connect to a branch circuit, it can access 240 volts. If the branch circuit connects to one bus bar, you will get 120 volts of power. You can determine the voltage of each branch circuit by looking at the number of bus bars to which it is connected. The panel has a pair of bus bars that provide 120V each. The panel distributes the electricity from the wires to the other branch circuits. Regardless of where they pass, these wires will eventually stop at the service panel. Most homes have two 120V service wires that will either pass overhead or underground.

Simply put, power reaches your home via the service panel. The Spruce gave a basic explanation of the workings of a home’s electrical service.

It can affect the number and size of the equipment you can run in your home.

The amperage of the electrical service is not random. It shows you the volume of electricity that can flow through your home. Your home’s electrical service size reveals the total capacity available to you. 125A is the total volume of electricity the bus bars can safely carry. If you see 125 amps in the panel, your electrical service has a capacity of 125 amps. But what do those terms mean? If your panel shows that you have 125-amp service, is that good or bad? Should you upgrade the amp service or leave it alone? This guide will give you an idea of what your amp service means and what you should do about it. You have probably heard your electrician refer to the amps of your electrical service.
