6mm shower


musicspark

Question

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?

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? ;\

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?!

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=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??

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:);)

Yes but the cable is also ru through a loft with rockwool insuation which would surely derate the capacity of the cable?

should be a serial number, to ring up or look on web

special a question, say the appliance was put on a 6mm 45amp mcb and the appliiance draws 51 amps, 6 extra amps i dont think will trip any time soon. will it be a prob on the cable or will it take it untill the mcb trips
