Ground fault outlets

[Grubster]

I went looking for a GFI outlet today for my small pool pump, none to be had that I could find. Do I have to put a ground fault interrupter breaker in the main panel?

Thailand uses the UK terms RCD or RCBO (includes over current) the local shop assistants won't understand GFI.

 

RCD outlets are available, but they're expensive and difficult to come by. Look for one of the Safe-T-Cut specialist stalls in Tesco and the like.

You can put an RCD / RCBO in the panel or buy a little stand-alone RCBO (about 500 Baht with a little box) and protect your pump with that.

Just to add... a GFI or GFCI is the term used for ground fault protection commonly used in the states.  It is always back-end protection usually in the form of a receptacle.  They are functionally identical to the front-end protection used here (RCD/RCBO).  Due to the way electric is supplied in the states, front-end protection is just not feasible there.  I have seen the type here where the "GFCI" plugs into a receptacle and the device to be protected is then plugged into that.  

 

BUT - for a pump, I would just properly ground it and forget about it.

Thanks, I see that my electrician who did a gorgeous job on my home put RCBO's in the breaker boxes for all the water heaters, I can now point to those and he will understand what I mean, I think he used a small wall mounted one on my mother in laws toilet room, I think that may suffice for this ap. I will not plug this small pool pump into an outlet that does not have it. I don't think it would be right to put a RCBO circuit breaker on the outlet circuit that serves many outlets would it? I am thinking these are to be dedicated.

That's how it's done in the UK, often a split board with two RCDs each feeding half the circuits.

 

UK regs require any cable buried less than 50mm deep in a wall needs an RCD at the source end, so pretty much everything has some form of RCD.

 

Just replace the breaker that feeds the pool pump outlet with an RCBO, job done

This is one of those 12" wide vinyl pools with a very cheap little plastic pump that has only a two prong plug, the instructions say it must be ground fault protected.

Thanks a lot Crossy as two of the RCBO breakers for water heaters are not in use so this is an easy fix he can do when he gets here in a few minutes. Happy about that I am      Cheers

Sorry, but did he run 2 wires through the RCBO to the water heater or 3 wires to the water heater? 2 wires through the RCBO and an earth wire.
I could be corrected about my thinking on this.
