Electric shower using trunking

[Bradley6969]

Hi, not done many showers 9.5kw shower, clipped direct, 10mm cable, 40amp MCB no issues the thing I wanted to ask was, there was existing feed too small so new cable all newish tiles so going to run some 25x16mm trunking now do many shower have any knockouts on top? Or will I have to make my own and seal up?
Thanks

Many of them do have a top surface entry option.
You don't normally need to apply sealant as they are designed so that any water entering the top knockout will run out of the bottom and not flow in to any of the connections.
Some advise against sealing as it can trap any water that does get in and cause more harm than good.

A cable contained in trunking is not clipped direct.

I see some trunking, wouldn't call it clipped direct...

I think that the O.P. is referring to the short run between the ceiling and shower in the bathroom as it has been newly retiled.
