What size breaker do I need for a pool heater?

30-50 amps





Gas pool heaters will also typically have conduit from the time clock, to carry power into the heater, whereas pool heat pumps will require a dedicated breaker, of substantial amperage, usually 30-50 amps.

What kind of breaker do I need for a pool pump?

The National Electric Code requires that all swimming pool pumps be connected to a GFCI breaker.

Why does my pool heater keep tripping the breaker?

When your heat pump’s condenser coil is dirty, your unit has to run at a higher capacity to produce the same amount of cooling or heating. This causes the breaker to trip. Regularly maintaining your heat pump can help ward off this issue.

Can I run pool pump and heater on same circuit?

If you do run them on the same line, you should at least put a switch for each locally. Eg, have the line come into a 2-gang junction box, then use one double-pole switch for each. That way you can still control the power to the pump and heater independently.

Can I install a pool heater myself?





Absolutely yes you can install a pool heater yourself without being a plumber. It is recommended to have a friend help you set it up so you don’t get hurt. But, you will need to be very comfortable and take safety seriously. Read the instructions on how to install a pool heater.

Does 240v pool pump need GFCI?

GFCI protection is now essentially required for all receptacles that supply power above the low-voltage contact limit to equipment that handles pool water. This requirement is in addition to the GFCI protection required for 120V through 240V, single-phase pool pump motors.

How many amps do you need to run a pool pump?

If you need to know the electrical requirements for your inground pool, here is a list of common pool equipment and the approximate volts and amps required for each: Pool Pump: 240v, 10amps. Salt Water Chlorinator: 240v, approx 5-8 amps. Pool Heat Pump: 240v, 50 amps.

Does a pool pump need to be on its own circuit?

So, if the wire in the extension cord is too thin then the cord can eventually burn up or overheat causing the pump not to run. Also, because the pump uses a lot of power, the outlet that you plug the extension cord into should be on what is called a “dedicated circuit”.

What size breaker do I need?



How do I size a breaker? Generally, you should size a breaker for 125% of the load (or 25% extra capacity) and no less. Oversized breakers can allow wires to heat above safety levels without stopping the current. On the other hand, undersized breakers may continuously trip under normal operation.

How do you rewire a pool pump?

Quote from the video:
Quote from Youtube video: If you are wiring for 115 volts the three wires to the pool pump will be black white and green attach the green wire under the ground screw. Attach the white wire to the terminal 1 of line 1 attach.

Do you need a disconnect for a pool heater?

A maintenance disconnect is required for shutting off power to pool or spa pumps, filters, and other utilization equipment. The disconnect must be installed within sight of the pool or spa but can be no closer than 5 feet from the pool or spa so that you cannot turn the power on or off while leaning out of the water.

How do you wire a 220v pool pump?



Quote from the video:
Quote from Youtube video: A 220 volt pump up to a 110 breaker it'll probably burn out within a minute or so and so basically the wiring is very simple you have load one and load two you just hook up each wire to each section

Do pool pumps run on 110 or 220?

Connecting the wrong power supply to your pool pump can result in serious damage. Using an 110v connection on a pump that requires a 220v supply can result in your pump running slowly or not working at all. Applying a 220v supply to a pump that needs an 110v input could damage your unit beyond repair.

How do you wire a GFCI breaker for a pool pump?

(1) Install a 20 amp GFCI at the main breaker panel for the dedicated 240 line for the pool pump. Neutral wire from GFCI attaches to ground/neutral bus which is the same at the main. (2) Add 240 Disconnect by pool pump. (3) Add Intermatic PS3000 surge protector by connecting it to disconnect.

Is my pool pump 110 or 220?

If you turn it on and the display lights it is probably working. In any event, if you turn on the meter, turn the knob to the 750 ACV position, put the leads on the wires in the pump (white and black or black and black) you would be able to see if you have 115 volts or 230 volts.

How do I change my pool pump from 220 to 110?



Quote from the video:
Quote from Youtube video: In order to change this to 110. Take a pair of pliers. And just gently turn this. And now you can see we're at 115.. Now you have heard me say 110 115 120 doesn't matter that's all the same.

How can you tell if you have a 110 or 220 breaker?

The Difference Between a 110 and a 220 Outlet

  1. The 220 outlet is larger, and it’s usually round and black or dark brown, not white.
  2. It can have three slots or four. Four-slot outlets have a ground wire. …
  3. There is only one outlet, unlike 110 outlets, which are almost always installed in pairs called duplexes.


What voltage are most pool pumps?

Your Pump Motor Label



Let us explain. Manufactures make motors 115V, 230V, or 115/ 230V. So, if your motor lists one specific voltage, it’s safe to go with that. However, if you have a dual speed motor, one compatible with both 115V AND 230V, then you’re back to square one.

Can you run a 230v motor on 110v?



220v and 110v systems are compatible, they just need a voltage converter. While most of the world uses 220-volt electricity, the United States uses a combination of 220v and 110v appliances. The lower 110v wiring is used for most standard appliances and devices, such as computers, TVs and table lamps.

What’s the difference between 230 volt and 115 volt?

A 115 volt circuit is wired with one hot wire that carries the current with one neutral and a ground wire; while 230 volt circuits are wired with two hot wires and a ground. The amp load is split between the two hot wires which provides the somewhat deceptive amp draw on the motor label.
