SELV to supply Shower Pump

[Nitell]

Hello

I once had an Electric Shower Pump in the bathroom on a SELV unit. That pump was removed some time ago.

Now I plan to fit a pump such as the Monsoon or Salamander.

Instead of fitting a FCU would it be Okay to connect the pump to the SELV ?

Thank you for all replies/advice.

SELV - Separated Extra Low Voltage - is <50V AC, or <120V DC, so not if the pump requires 230V AC.

Or yes if it is an ELV pump of the same voltage as the previous one.

Using the ELV supply you have is not an alternative to using an FCU - either you buy an ELV pump or you buy a 230V one, and what you buy will dictate how you supply it. Whatever you buy, once you have it, there will be no alternatives to how it's supplied.

Thank you to all.

I will get rid of the SELV and use FCU.

I expect that the pump will require the circuit supplying the pump to be protected by a 30mA RCD. IS it?

If not, you may need an FCU with RCD functionality. Something like this

I will get rid of the SELV and use FCU.

Why?

Why?

Possibly because the two model ranges of pump he has mentioned are 230V AC?

Well if that is the case, then in the name of all that is IQ-bigger-than-shoe-size, WOE did the OP ask "Instead of fitting a FCU would it be Okay to connect the pump to the SELV ?"

That'd most likely be because he didn't, at that time, understand what SELV was.

And this supply has nothing on it showing what its output voltage is, I suppose.
