Hi Guys,
I am installing an electric shower. I am going to lay the cable and then get a spark to sign-off and do final connections.
I am just ordering the materials and after some guidence on the cable size from someone who had access to a copy to the 17th edition.
Shower: 10.5KW
Cable run: around 18m
Calculated current @ 230v: 45.6A
The cable will be run primarily in un-insuallted voids - such as the floor space etc but will be channelled into brick walls for around 2-3 meters.
I was intending on getting a 50Amp RCBO as the RCD side of my board is full. Or could I get away with a 45A RCBO?
In terms of switch - was going to get 45A cooker switch. I have not seen a 50A rated switch, other than a pull cord one and I don't want a pull cord. Will a 45A switch be ok?
In terms of cable - was going to use 10mm2. Is that suffiicient, or do I need to go to 16mm2?
Would really appreciate the advice.
Cheers
James
