Bathroom Electric Circuit

[Silver_Hawk]

I've completely gutted my bathroom in my 1950's house....everything is gone, so I can start from scratch.

The only electrics that are needed in the bathroom (apart from overhead lighting) are a couple of 350 watt heated towel rails, a shaving socket, 3 amp power shower (not an electric shower!), and some mirror lights.

I have a dedicated 2.5 mm T&E running from the new consumer unit to the 2KW immersion heater which is close to the bathroom. It is protected by a 16 amp MCB and is only used rarely and usually at night for Economy 7.

Any reason why I cannot use this circuit to power the above appliances in a radial layout? Each appliance would have its FCU hidden in the airing cupboard where the hot water tank is. I don't want to break into the normal ring main unnecessarily.
Is the 16 Amp MCB sufficient?

Thanks for your advice.

It is not good practice to spur anything else off the immersion circuit, especially as when in use it is near to circuit capacity.

Work in bathrooms is notifiable to your LABC under Part P of The Building Regulations.

Isn't there a reg that says that any water heater with a capacity of 15 litres or more should be supplied off it's own dedicated circuit??

I don't think it is a reg as such, more of a recommendation in the OSG.
Still don't like the idea of doing it that way though.

Yeh, I knew that I'd read it some where, just checked the regs and can't find any mention of it, so it must be in the OSG.

Tis. Something like:

Immersion Heaters, fitted to storage vessels > 15l.......are supplied by their own separate circuits.

Under table 8A from memory.

Secure,
Was in your neck of the woods today, had to go up yo Oldham to fix some lights in a nursing home. Took me 1 3/4 hrs to get there, 2 hrs to sort it out, and 2 1/2 hours to get home. God knows how I'm going to bill that, the builder is going to see his anus if I try and charge a whole day for just 2 hrs work

 

[securespark]

Didn't you give him an idea before you started??

 

[nozspark]

No,
He knows exactly where I live (he lives a couple of miles away) and where the property is - he know's it's at least a 3hr round trip in good traffic, he also knows what I charge per hour. Asked me to go there as an emergency. His plumber is local to us aswell and he's been there too!

It's just if I try and hit him for £200 for 2 hrs work he's going to see his bum (upgrading MCB to 10A) - 14 fittings 40 odd lamps, it's not surprising the MCB was tripping occasionally! -
