6mm shower

[musicspark]

I have been asked to reconnect a shower which was installed "two or three years ago"

The customer is therefore reluctant to believe there can be anything wrong.

The shower is a "Myra Sport" on a 6mm cable It has a nice Merlin Guerin RCD next to the CU but on a 40A breaker. I realise that something has to change but I don't know the rating of this model of shower can anyone help?

Mira Sport come in a range of sizes. Often it will be Mira Sport 7.5 etc

 

[Apache]

I don't mean it's a 7500W I mean there is a number that will say

Thanks Apache,

But that don't help much do it?

do you know if there is a plate anywhere inside this appliance which would give me the info ; or do I have to use a bag of bones to determine the wattage?

Perhaps a spiritualist or soothsayer? ; \

Thanks Apache,But that don't help much do it?

No.

Have you taken the cover off? No rating plate inside?

If you've got a clamp meter turn the other breakers off, whack it around a meter tail and measure it?!

or cable melting?

[musicspark]

Smaller breaker would be the easiest if the shower is small enough

Not sure why you are saying something has to change??

any way...

as Apache said.. Mira Sport? what power rating is it?

e.g...

http://www.mirashowers.co.uk/onlinecatalog/results.htm?sectionName=Electrichttp://www.mirashowers.co.uk/onlinecatalog/results.htm?sectionName=Electric showers&filter[bRAND_NAME]=Sport

6.0mm cable, clipped direct could carry 47Amps...

table 6F page 134 on-site guide..

And according to table 7.1 page 50 on-site-guide

a 40Amp 6.0mm circuit (inst method C) can be upto 40m long!

so 40amp MCB could provide power for 40x230 = 9.2kWatt.

So if your cable is clipped direct, the run is less than 40m

and the shower is 9.0kw or less...

what needs to change??

 

[Apache]

there should be something that gives a rating.........

sticker on the back? model number you can google?

 

[Apache]

what needs to change??

Underpants? Might get hit by a bus?

 

[tom1]

[Apache]

what it if turns out to be a 10.6kw shower

tell em to take it back and get a smaller rating model..

or pay for cable upgrade!

10600/230 = 46+ amps...

IMHO 10.0mm & 50A MCB
