Im trying to get my head around the CU requirements for a TT system. If i was to fit a CU with RCBO's protecting all the circuits, would the main CU switch 100A or 63A need to be a time delayed RCD or could it just be a straight forward isolator switch as the RCD protection is provided by the...

FYI, I have just been to a place where a galaxy 1000 was fitted by the builder. Its an 8,5KW. First thing was it had not been put on the RCD side of the board, when i on behalf of the owner questioned this with the builder he claims no mention was made of an RCD. Second thing, to turn the shower...

Just read through this and noticed the question about the cost of PI and PL insurance. My PI is £240 per year which gives me 2m cover. This policy is purely for electrical testing and certification. My PL insurance which covers the rest is £130 per year for 1m cover. I only do domestic work...

But that result is a pass its <3.5mA

Ive not seen any mention of an RCD although i assume it it part of the replacement CU but thought i would ask.

[/url] Grizzly has posted the link and as i said the leakage test is not compulsory. Also i note that in some of the replies the figure of .75ma has been raised. for a washing machine which is classed as a stationary or movable appliance its 3.5ma or less. Dont know if that makes a...

From memory the leakage test is not a "compulsory" test. If you carry out a class1 IT test for example it will not perform the leakage test at all.

Thanks all for the responses its settled my mind a bit more. Woody i agree thats what a survey should do but as i have found and others said a "standard" building survey does not seem to give any advice on the potential level of a problem. It really did seem to be a statement of the bl**dy...

Hi, I am looking at a bungalow to buy and went around it the other day. Inside i noticed quite a few cracks in the plaster all small in width (around 1mm)but numerous. They run horizontally vertically and in some cases fan out. They are on the inside of the external walls and on some of the...

I agree partially and thats why i said if you dont need it. But if, and i do say if you get a 1k per year clear return and i think its tax free ? over the 20year period you stll get a slightly better return, if interest rates stay below 3%. I accept that is unlikely. No axe to grind...

I do know a couple of people who have this done and it did cost in the region of 12k one was higher but i think he has 6 panels so about 2.4 kw. It doesnt suprise me that they are getting cheaper, Persimon homes for one are building them into their new houses and if you have 10k sitting in a...

As requested the outcome. I should have taken pictures but anyway, the Aurora lights with the adjustable springs worked, in so far as it could cope withthe double ceiling thickness and lath. However the ceiling had been so badly damaged that the collar didnt really hide the mess. I tried to...

Not sure what they are for . They basically are a piece of steel/iron? rod which is bolted to two plates of steel/iron which enclose the rafter about a thrid of the way up from the ceiling. The steel then forms the horizontal of the A. Looking at the design you can shorten the rod by tightening...

Hi , Sorry i might be using the wrong terminology. I am looking to buy a house 150years old solid brick walls. I have had the survey done and no real suprises, theres damp as expected. However the roof has been renewed ie new slates and some rafters. The surveyor mentioned the presence of...

Just once you catch something just once and the whole world knows :) I will let you know the outcome once the go ahead is given. Thanks for your help

Hi Not actually checked the link yet but i got this back from aurora when i mailed them yesterday. We have a few options for you, please see one below. A2-DLM943 - 240V GU10 Pressed Steel IP65 Downlight Fire Protection this is a suitable product, this is also available in low voltage...

Do all the JCC range have these adjustable positions. The idea looks perfect unfortunately the hole is about 70mm and that one is 62mm. I note there are others in the TLC catalogue but i cant see the clip holders. Thanks for the pointer a great help

Thanks but WF is ?

Your right about the root cause but i can hold my hands p and say not me guv, a handyman used to come in and do it. I want to go CFL and wanted to use the click with megaman units. I like IP65 a because its in a basement with a living room and floorbaords above and b they have the little silicon...

Does anyone know a brand of downlighters that have longer than normal clamp springs. Some downlights in a basement are basically falling out of the ceiling. When i inspected them the holes have been ripped ragged everytime someone changesthe lamp. I think the reason for this is that the...
