40A MCB for a 10.8 Kw shower? 10800/230 = 46.95 A. Surely a 50A MCB? Maybe my knowledge is lacking. Perhaps you've used correction factors not mentioned? Just curious.
Great video as always nick and Adam start my own course in September can’t wait but nervous learnt so much from your content already can’t wait for future content
I've been watching your videos for a while Nick, always great work. Just a quick question if you don't mind. For a 9.0Kw shower what size cable would you use? 10mm, or would 6mm do the job?
My electric box is under the stairs,would I need to rip up carpet for cable to go from electric box to upstairs bathroom? This would be a first time installation of electric shower
You said in the vid that you don't sweep up. However I am sure I saw one of those 'sweeping brush' type things in your van. Did a plumber put it there as a joke? 🤣
@@barnabybottake your time and install these guys properly and they are sweet. Everybody will have their go to. Crabtree are a winner for me from switches to c/u's.....
It's worth mentioning that the inclusion of a local isolator is a decision for the designer and not the manufacturer of the fixed appliance. What were your considerations when deciding to include one?
@@barnabybot We have the same issue on lighting circuits, but we don't have double-pole isolation available on those. Come to think of it, socket circuits don't have a convenient method of removing neutral faults either, apart from disconnecting at the neutral bar. Why do we need double-pole switching for showers and not for other circuits?
@@westinthewest there is no requirement to do so but as the shower will need to serviced by persons who are not electricians it makes sense to be able to have a dedicated isolator
Not your fault in the slightest but I have concerns about how watertight it's all going to be on the plumbing side of things, especially if that specific type of electric shower doesn't require an external silicone seal.
Nicely done. one thing I wish would be abolished completely is shower isolators ! Adding a joint in a 10mm cable, usually in accessories that are too tight, and pulling heavy load is just always asking for a problem. probably the most common thing to find burned out too just proves it.
Isolators don't need to be abolished. They should only be fitted by people who have thought of a reason to provide one, and that does not include 'better safe than sorry' or 'it's what we've always done'. Don't blame it on the manufacturer's instructions either. You're the designer and it's you who signs the certificate - not Triton.
@@westinthewest Here's a reason. In this particular case the shower is on a shared RCD. So if there is a fault on neutral the customer can't isolate it by turning off the MCB thus losing all the circuits on that RCD side til they can get hold of a sparks to come round and have a look.
