Hot Tub
- Thread starter mdbalson
- Start date
The hot tub my mum is looking at getting, says it needs a 25 Amp circuit, & it says that the Air Blower is 1300W, plus the Heater at 3kW
The run of SWA will be 42m from the Outside JB to where the Hot Tub will go, plus 3m of T+E from the JB to the House CCU.
I was going to have the hot tub on a RCBO in the house CCU,& use 3 core SWA.
So what size cable would be needed

Pictures of the tools I used to fit a hot tub
Just a bit iof fun MDB, but being serious you should spend time planning ahead. You did your shed and loft last year, now you are in the middle of a kitchen refurb and are now looking at more outside work.

What do you mean by this
The 42 metres is the length of the run of the SWA from the outside JB to where the Hot tub will be.
Have you done the City & Guilds 2381 16th edition regulations course yet ? As basic cable calculations are covered on this course. Mind i can remember doing cable calcs in my 1st year of college on the 2360 part 1 course, We used the tables in BS7671 and the OSG.
I have done the C & G 2330 Level 2 course, & I am doing the C&G 6127 in Refri. & A/C
I passed my cycling proficiency test but I found it in no way prepared me to install and test electrical installations.
I passed my driving test but I found it no way prepared me for driving on roads among the other car users.......
If you are only installing the small 3m length, then 6 or 10mm will eat it - You can then calculate the SWA size at a later date.
