Can i ask why re the metal clad? Might be a stupid question!

Hi Guys Im replacing a DB in a domestic property with a TT Supply. Never done much with TT systems before. Am i ok just fitting a stand split cu with 2 x 30mA RCDS or do i need to also fit a 100mA RCD before the cu too? Any help appreciated?

Hi, im an electrician and am wondering what is the best way to locate an earth fault causing an rcd to trip? Are there any tips from good sparks out there who have sussed out quick ways to locate these faults. I kniw it varies on ring finals and lighting circuits but any advice and methods would...

I have told them that they have a large quantity of lamps and therefore will experience more lamps blowing, but the fact that there lamps are popping every other day throughout the house, more so in the kitchen baffles me?

Am i right in saying that C type have a slower reaction time of around 1.3 times slower than B? What do you think my problem could be though? Im pulling my hair out. Lol

on circuit 1, there is about 20ish 40w candle bulbs. On circuit 2 there is 10 X 50w MR16's 1 4' fluorescent and 3 50w GU10 (the kitchen) Cheers

Thanks for your replies!! I have already carried out a periodic inspection on the property, everything ok and within limits. I have measured the current in the circuit which is about 4 amp. I have told the customer I am going to go back next week free of charge for them and test both...

I have 2 lighting circuits. One feeding kitchen, garage and utility. One feeding lounge, diner and bedrooms. I installed a new 3 way GU10 halogen fitting in the kitchen approx 3 months ago, since then the individual GU10 lamps are blowing almost every week, In turn it trips the MCB. There are...

Thanks for the quick reply! I have learnt something else today! Ive just drawn it out on paper and I suppose it makes no odds as its still effectivly connected just at the other end of the strap wires! Cheers

Hi I have 3 switches in a house and im installing 2x 2way switches and 1 intermediate switch. I know normally I would take Feed and switch wire to one 2 way switch and connect them across L1 AND L2, but is it possible to take the Feed and Switch wire to the intermediate switch and connect??

I have just laid some new decking in my garden, but the decking that has been down 2 years is starting to get green type of algae or moss on it as it is in the shade most of the day! What is the best way to clean it off ready for oiling??

Hi, I'm rewiring a large property and installing shaver outlets in all bathrooms, one bathroom is a wetroom. Never come across this before what's are the regulations regarding this? Thanks in advance.

Yes I agree that a light fitting that is designed for steamy and moist enviroments is a better solution but any light can be installed in a bathroom providing the lowest connection of conductors is above 2.25m

HowJohor can I stop cracks appearing between ceiling and Walls in my house? Only happens upstairs!

Hi all! Was back at the customers today and I think iv got it sorted! Measured voltages as suggested. With only the light on, got 219v soon as shower and oven and kettle went on voltage dropped to 211v and the fitting started to flash untill the loading was reduced! Iv just put a hf fitting up...

No I haven't actually seen it flash but customer just said it flashes so I would presume on and off! I think I'll have to do wat was suggested and measure the voltage at the fitting when oven off then turn oven on and see wat I get! If it is the volt drop causing the problem then maybe get...

Could you explain how fitting a hf fitting could be better? Excuse my ignorance! Are you saying that if the incoming voltage is lower than normal then when a piece of high current using equipment is turned on the voltage drops on other circuits?

When u say upstream do u mean at the distribution board? Busbar?

Hi was at a job today as they said there kitchen light was flashing at odd times during the day. They already had 2 electricians out previous to me and they couldnt solve it either! Both replaced the light thinking it was a faulty light, so in all it has had 3 fluorescent lights?????? When I...

So I am getting the general idea that this additional isolator is not required! I thought it was an addition in the 17th edition that all board changes must have a isolator fitted!
