What You Should Know About Wiring Pool Circuits in North Scottsdale, AZ

November 7, 2018 10:59 pm Published by Leave your thoughts

The vast majority of pools that are built these days come built with a sub-panel located at the equipment pad that houses the main breakers for all its electrical equipment, including the underwater lights, pump, air blower, electrical outlet (GFCI), time clocks, automatic cover, electronic heater, control systems and more. This sub-panel is also tied into the main electrical panel inside your house, which powers the pool.

In some older pools, there might be a switch that turns on the filter pump and the underwater light, but over time, as the technology has changed and the understanding of electricity has become more sophisticated, that has gone out of style.

Here’s some information about pool circuits in North Scottsdale, AZ and wiring the pool pump from the circuit.

Wiring the pump

In-ground pool pumps generally have reversible voltage, except for pumps that are greater than 2hp, which will require 220V (reversible accept 220V or 110V). The reversible pumps generally come prepared to accept 220V, but to switch to 110V all it takes is following the included instructions. If you have an above-ground pool pump, though, it will generally only come for 115V, and will be wired with a power cord you must plug into a GFCI outlet.

If you are using a single-speed pool pump motor of any voltage, there are going to be three wires that transport power from the breaker, switch or timer and connect it to the motor’s terminal board. The green grounding wire connects to the green grounding screw, and the other pair of leads will connect to two power terminals marked L1 and L2—for these, it doesn’t matter which wire you send to which terminal. Use a pair of needle nose pliers to hook the wire and slide it under the brass screw, then tighten it as firmly as you can—the hook for the wire should be pointed toward the right, meaning when you tighten the screw clockwise it will pull the wire into the screw along with it.

If you have a two-speed pump, this is going to be a little bit of a different process. There will be four wires instead of three, the fourth being the low-speed wire. You can use just three wires, but to convert to dual speed you’ll have to add the fourth wire. You’ll also need to switch out the time clock to a two-speed clock, or a specific type of digital time clock that can take the fourth wire.

Finally, if you have a variable speed pump, this is actually a simpler process than wiring a two-speed pump. You can use the standard three-wire system here, and do not have to use a time clock, because the pump can be programmed for run times in a way that replaces the functionality of the time clock.
