Hot tubbery with Phil the f@%*ing Plumber

Warning! Contains a plumber: some viewers may find this distressing.

This was one of our first jobs back in the spring following Nige having been on furlough for two months and involves a hot tub going in at the request of our old mukker Phil, who… perhaps… won’t be quite so friendly toward us once he sees this video…

Anyway, there’s a lot of nonsense in this and some ‘mature’ scenes and chatter… so don’t watch it. Seriously, you don’t even get to see the flimmin’ hot-tub at the end. For anyone foolishly ignoring this sage advice, some chapters are below:

00:00 Mindless van-chat.
10:07 Phil the f***ing Plumber.
11:51 Mindless site-surveying chat.
18:25 Drilling an ‘ole.
20:25 Mindless Huel chat.
21:10 Planning the heist.
36:37 Installation begins.
1:08:18 Escape from Grafton Flyford.

Regarding hot tubs, there are different ways and means. We went for a TT install and I explain the reasons why in this presentation. That doesn’t mean it’s big, hard or clever or that we got it right… or for that matter anyone else got it wrong if they’ve done it differently. It’s simply one of those jobs where you refer to many publications to try and figure out just what you’re supposed to be doing as the guidance and manufacturers aren’t terribly helpful.

We used MCG gear from CEF, and the main reason for that being the 100ma Type-S Type-A fault protection RCD was readily available and keenly priced, plus MCG had a low-cost steel enclosure it could be housed in. They also had double-pole RCBOs, 40A C-Curve Type-AC, so it ticked all the boxes. My thanks to Lee at CEF Warwick who pulled out the stops to grab the RCBO for us from another branch at the last minute after I found I’d purchased the wrong one. Lee, we salute you!

The job as planned was for the rotary isolator to be on the back wall facing the field so it would be out of line-of-sight, but on the day, Phil asked us to place it onto the side wall. That left us short of flexi-conduit as we hadn’t brought enough for the new position. A bit of a shame as it’s less aesthetically pleasing. The patio lights are Class II, so no need to worry about simultaneous touch contact between Class I parts and TT earthing.

The testing of the 100mA RCD at the end seems to have been lost. Sorry. That was tested from the output of the device itself as, obviously, if you connect the tester downstream then the 30mA RCBO will get in the way.
