Hey all, I'm new here and this is my first post !
Been handed a job from close friends to install feed to their new hot tub which is on order, not done one before and its brochure shows it needs 2 feeds ? 1 x 4mm for 16A rated heater elements and 1 x 6mm for 25A pumps and jets. This seems a bit much unless just covering start up current.
House is fed on a TN-C-S and BS1361 100A Type 2 service cut out.
Feed would be 12 mtr run or so to tub via a rotary isolator I expect and apparently sales guy has said it will be via a commando plug.
Question: would it be o.k. to run feed from a Type C RCBO from Hager CU inside and earth saw cable as normal with cw glands to isolator ? or do I connect cu end as normal and leave feed from isolator to hot tub earth separate from earth on swa and earth hot tub end to a new rod as a TT ?
also are there any distances that must be observed between isolator switch and tub ?
Any and all info / help would be very appreciated. Thanks all.
