Was fixing a leak and noticed this. Is this OK in as much as the bath is not earthed in any way, plastic piping.

Well the frame of the bath is by the manufacture via CPC of circuit. The bath is fibreglass/acrylic and earthing that would serve no purpose, nor would earthing plastic pipework.

Not a spark, why does the manufacturer supply the earth wire and earthing points?

On acrylic baths, they don't - how could they?

Look at the picture, you can see the earth symbol on the metal frame. You can't see it on the motor but it is there.

Just trying to get my head around this one.

That's bonding, not earthing. You can't electrically bond something which is non-conductive. Presumably the motor is connected using twin and earth cable?

Amateurs error, (mine not yours) but I still can't get my head around what the wire connecting the motor casing and the frame is for. Explanation for layman would be appreciated.

What is that piece of metal?
There is only one.
Is it a support for the pump?

Not sure why it would need earthing or bonding.
Perhaps it has a tag just in case which would encourage people to use it even if not required.

To prevent a voltage difference between the two pieces of metal in the event of a fault. There's very little chance of that anyway.

Extension of bath support. One piece.

Thanks.

So - probably doesn't need earthing or bonding.

CBA to look, but does the accessibility of it with/without a tool make a difference? If the body of the pump is connected to it then it's an exposed-conductive-part, not an extraneous one.

If there is an earthing terminal on the frame, then this could in the event of you having metalic pipework, then this could be cross (supplementary) bonded to the pipework. Assuming that supplementary bonding is required and the provisions of any additional RCD protection does not take care of this matter.

Cheers all.
