Hello Fellow traders, Have started a electrical contracting business, this year one man operation in north east england, and am generally doing OK. However unlike a painting decorating the repeat business from domestic customers is low as after rewiring a house thats it for 25 years, and...

dont forget to heat shrink the crimp joint as well!

if your brave enough to leave a contractor in your house alone. Why not get 2 prices in for occupied and unoccupied it does make a huge difference as floorboards/ furniture carpets only have to be lifted once and the power does not have to be on all the time. then with the cheaper price with the...

uPDATE Thanks for the interesting replies. Did a current load test and the shower is ok I know the cable is OK as its new and tested as is shower switch, I feel the weakness is the aged wylex unit and will be replaced, many thanks for the tips. Its nice to get some support from time to time...

1 yes 2 clamp meter never had the need to use one but I'm going to get one, and again there is no need to do any current load tests for a part P. Fault finding is different 3 I'm totally puzzled by this situation not seen anything like it before Iknow the cables OK so why should it overheat...

i fitted one of these a while back now i had a few issues as well. But if i remember correctly if the humidistat is connected up then this blocks the overun timer i think also cranked the humidistat to its min value as with no steam you cant really test it

As far as part p goes there is formal arrangement or indeed any requirement in any electrical installation test part p or not for load currents to be measured if a item is ce marked and duly rated. The reason as to my uncertainty over the white one way wylex is that it is not ce marked and...

PART p hmmm FORGIVE ME IF I'M WRONG.....But like for like not part P, repairs to damaged cable not part P, and who said i was not part P anyway

sorry no can do photo, all I did was re run a new cable and reconnected it into the old switchgear like for like but upgraded the to a plug in mcb from a 3036

thanks for all the replys the advice is great and I thank you all (please dont stop)

it's not on a rcd, so if i do replace it then I probably will (surprised to learn that there is no requirement in the regs nor do the niceic stipulate that its is done, logic is that its a class 2 device in essence and will make no difference only if someone drills the supply cable. (like any...

cream

there is no markings on the main switch it is that old nor on the inside of it there is a 240v reference on the inside and the number 30 moulded into the plastic in tiny letters but not 30A, i looked at the latest wylex rewirable one ways and they are rated to 45amp.

sorry,.. no old cable melt evidence at the wylex nor new one. althogh there is a couple of brown marks looks like a fuse rupturing on the front cover of the wylex.

oh and there is a big label on the inside of shower that says 9500 watts load 39.5 amps 240 37 ish at 230v Shower has not been in use for a year and there was signs of the old cable melting at the switch, even a new pull switch 45a has been installed. Could a lime scale buildup make it draw...

Brand new Proteus Plug in MCB (replacement for rewireable fuse) I have not load tested as I dont have a clamp meter. I've contemplated replacing the wylex but I feel it my be unnecessary

thanks for the advice, In more detal the one way fuse board wylex originally had a 30 rewireable fuse and melted the original but old 6mm cable (imperial equivalent)on the 9.5 kw shower.(40 amp load) The cable only needs to be 6mm it carries 47amps look in your regs. the cable is brand new...

Problem I have 9.5 Kw shower on a 6mm t&e wired through a 45a plug in mcb in a old one way wylex, cable is tested ok but circuit breaker getting very hot when shower is on, no insulation cable capacity 47 amps, connections good and tight, puzzled to the problem
