It is NOT permitted to share a neutral in any other situation. If you were to share a neutral with two breakers on the same leg of a panel, both circuits could draw the breaker limit (lets say 15A) making the shared neutral as much as 30A return current!

Re: Two circuits in the same box (outlet/switch) The only real limitation in a box is wire-fill and low-voltage separation. Other than that you can have as many circuits as you have devices in the box, as long as you have adequate room in the box for splices and connections.

1. You can share a single ground but it must be sized for the largest circuit running in the conduit. 2. Yes it is ok.

There is no problem with putting more than one GFI on a circuit. +1 This is what my electrician told me to do, as I want to add an outside outlet, without having to go back in to reset the GFCI.

According to IRC 2012, all 125-volt, single-phase, 15- or 20-ampere receptacles installed in garages and grade-level portions of unfinished accessory buildings used for storage or work areas shall have ground-fault circuit-interrupter protection for personnel.

-NEC requires GFCI protection for all pool pumps. A pool builder or electrician cannot install power to your pool pump per code without one. -Moisture from rain, sprinklers, or runoff causes GFCI breakers to trip as well.

Most often, when a GFCI “trips” it is the result of a faulty appliance plugged into the outlet or an outlet down circuit. Simply push the TEST button to turn power off to the circuit which should cause the RESET button to pop up. You will need to hit RESET to turn the GFCI back on.

A typical above ground pool pump will require a 20-amp breaker and use #12 gauge wire to deliver the electricity.

Typically, a pool pump needs to be on a dedicated circuit. Pool pumps use a lot of power; hence they function best when they have their circuit. But it is always best to save on energy by regulating the time the pump is on. If you have a residential pool, you can reduce the time you turn on your equipment.

Failing to do so will burn out the motor of your pool filter. Invest in a cord long enough and thick enough to handle the filter’s power. Most pool professionals recommend a 10- or 12-gauge cord in the event you absolutely must use an extension cord to hookup the filter.

You shouldn’t be installing over any buried electrical lines. You really shouldn’t be installing a pool any where near a wire that isn’t run fully encased in conduit and buried at least 6 inches down.

Moving your underground utility lines is easy as long as you know what you have to do. Once that’s out of the way, the safest method of digging up and relocating your utility lines will be using a special hydro excavation service that can remove the dirt around them without damaging them.

How Much Electricity Does Pool Equipment Use?

• Pool Pump: 240v, 10amps.
• Salt Water Chlorinator: 240v, approx 5-8 amps.
• Pool Heat Pump: 240v, 50 amps.
• LP/NG Pool Heater: 240v, 3 amps.
• Pool Lights: 12v, 3.5 watts each.
• Self-Contained Hot Tub: 240v 50 amps.
• Automatic Pool Cover: 220v, 5-7 amps OR 110v, 11-13 amps.

12 Amps

This standard package would include: An electrical permit. Labor and materials to wire standard pool components, which include: pump, light, pump timer, and installing one GFCI (ground-fault circuit interrupter) receptacle plug 10–20 feet from the pool.

The Amps are listed as 15.0 / 7.5 – which means that at 115V the motor draws 15A, and at 230V the draw is 7.5 Amps. For a larger motor over 2hp, you will commonly see only 230V listed and a single number to represent Amps used at maximum load. Note that the pump label or ‘name plate’ shows the Maximum Amp Draw.

If the motor is fully loaded, it will provide output power of 1 HP = (1 X 0.746) kW = 0.746kW. Electrical Input Power = (Output Power/Efficiency). Assuming 90% efficiency, Input Power = 0.746/0.9 = 0.83kW.

Assuming the motor runs at its full 0.5 HP capacity, that’s 373 W for 20 minutes, which is equivalent to 0.124 kWh. If energy in India costs 5 rupees per kWh, that’s about 0.62 rupees.
