You can use this wire sizing chart to look for the correct wire size according to your circuit breaker and the type of wire you are planning to use. The wire size you will use will depend on the size of the circuit breaker you use. But how would you know the correct size of the wire you are going to need? Stick around as that is what we are going to talk about next. So, when you go shopping for the things and tools you will need, you should include wires with the correct sizes. Therefore, it is vital that you also change the wirings and get rid of the old ones. There is a huge chance that the old wiring is starting to degrade. When replacing the pool sub-panel it also means replacing everything, including the wire. This is why you must conduct a thorough check-up before starting the replacement. If you use a lower or higher size breaker, the wires, devices, and circuits that are connected to the sub-panel might experience a short circuit or will overheat. This is the reason why you must use the correct breakers according to your swimming pool needs. When choosing the correct breaker for your pool subpanel, you should refer to the old sub-panel that you are replacing if and only if it does not go through heating up or a short circuit. Now that you know the correct sub panel you will use, it is now time to buy a new circuit breaker. Moreover, if you are using the old version of the pool pump, your sub-panel would be at 70 amp. Thus a sub panel with 60 amps would be enough to use. A 60 amps pool sub-panel is enough to supply the power you need, especially if you use a variable speed pool pump.Ī variable speed pool pump is known to be energy-efficient. Most commonly, 100 amps pool sub-panels are used when installing a large heat pump. Swimming pools usually have 60 to 100 amp sub-panels. It is best to do your research or use the old sub-panel as a reference. Remember, different pools have different electrical load requirements. In addition, checking the sub-panel before starting the replacement would also help you determine the number of circuits you need and the load for these circuits. You must keep an eye on these three mentioned issues as these are the most common ones. There are so many things that can happen to your sub-panel, like a burn, corrosion, or wrong electrical load. Do a Sub Panel Checkupĭoing a thorough check-up of the old sub-panel will help you know what is wrong with it. Here are some tips you must follow in properly replacing your electrical pool sub-panel safely. However, just like with any other part of your pool, your electrical sub-panel will also need replacement once in a while.

This way, you will never have to worry about the electrics of your pool, and you can easily light up and pump up your pool at any given time. This is vital in ensuring that you will have a proper extension of the wiring for multiple branch circuits into your swimming pool area. It would be best if you created an electrical sub-panel for your swimming pool’s electrical needs.
