230 volt pool pump motor wiring
230 volt pool pump motor wiring
(OP)
First, I am Mechanical not elecrical so i need some help with wiring a 230 volt pool pump motor. This is an AO Smith motor and the connections show L1, L2 and a ground. My panel has a 15amp dual breaker (for 230volt), which has two terminals. I asumed they would take a red and black wire to the motor, L1 and L2, plus the green ground wire. Would this be correct? There is no place on the motor for a white neutral line. Also, I was told by an electrician that I don't want to use a GFIC breaker for the motor. On the motor plate with the diagram, it says to use GFI protection. What would be the correct choice here?
Any help is appreciated.

If your voltage is 230V between a line and neutral, you connect those two wires. L1 to Line and L2 to neutral or vice versa. In this case you will only need a sigle pole breaker or a single fuse in the line.
If you have a system, such as in the USA, where you have 230V (or 240V) between two lines, you connect them to L1 and L2 and no neutral is required. In this case you will need a 2-pole breakers or fuses in both lines.
Ground (green) wire is always there.

And don't use the electrician who told you to not use a GFCI.
The NEC has a big chapter on swimming pools, etc and there is no way we can walk you through this in this forum. This is serious stuff from a safety perspective.

RE: 230 volt pool pump motor wiring
It may be a misunderstanding, or the pump may be exempt from the GFCI requirement due to distance seperation from the pool.
In the Canadian code, rule 68-202 (1) (b) gives the conditions under which the GFCI is not required.
Can someone check the NEC, please?

RE: 230 volt pool pump motor wiring
The NEC chapter on swimming pools, etc is long and complicated and was extensively revised for 2005. I'm not comfortable with trying to determine code compliance when we don't know much about the installation. Certainly any receptacle and any motor that is powered via a receptacle must have GFCI. If the motor nameplate says GFCI protection is required, it's hard to see how any exception in any code that would trump that, especially if the motor is UL labeled.
If it were me, I'd err on the side of caution and use a GFCI.
