Could perhaps be an led fitting with integral lamp, I.e. bulb can't be changed. Photo front on would help.

The plan is to re-use the existing 10mm2 Twin & Earth sub-main that runs the length of the main building with SWA to new building (total length of 35m ish). To extend the equipotential zone to the out-building would require laying a 10mm2 G/Y (or possibly 16mm2) along the length of the main...

Thanks for the replay Manator. I sorry but us townies do very lillte TT work! What I'm concerned about is getting a voltage on the fence from a fault current which could be sustained if the RCD fails? My thinking: I understand that Earth rods can be hazardest to four legged animal as the one...

I know the theorectical difference between TN-C-S and TN-C-S with PME but without a PME label on the head can I prove whether it is or not by test? (It is a 20 year old building in a TN-S area)

Hi, This is the scenario: 1) Scout hall with TN-C-S supply. 2) Outbuilding needs electricity supply. This is an equiment store with what I expect to be an "earthy" steel frame and "earthy" concrete floor (although I have not yet measured to see if frame is extraneous). Because of the TN-C-S...

I aways use Clickflow connectors whether I fit 12V or 240V down lights. It makes it easy to do R1 + R2 Tests and Zs as I haved made up some clickflow leads for my Megger 1552. I try to avoid 240V GU10 as the lamps are so energy inefficient and only last a few weeks!!! Most of the work can be...

Thanks for the replies. I guess it is a case of it being against the manufacturers instructions but might work ok in reality (but may vary between fans due to specific design of each manufacturers electronics!). I may give the client the choice in trying it - I suppose I would need to show a...

Yes, phaseliner are the ones I had seen before. However, to re-wire using a phaseliner would require an extra core from the switch drop - it is a tiled loft room, so I can't rewire the circuit without disturbing the the tiles. Does anyone have an opinion as to if the existing circuit ok with a...

I went to a property last week where the lights had failed in the ensuite bathroom. The circuit was controlled by a dimmer and had two 12V downlights and a fan on the circuit. The downlights each had their own transformer. I didn't look too hard at the fan but there was no indication that it...

Well what great pictures - and all at the same installation!! These sorts of pictures with discussion about the coding would make a brilliant training manual!

The legal difference between the two is also important for people in my situation: EIC - The work is covered by my "Public liability insurance". PIR - Professional opinion about the safe continued use the electrical system, requiring "Professional Indemnity Insurance". Which I don't currently...

I have recently fitted AICO Ei160RC series of heat and smoke detectors in a house. The lady of the house is deaf so the system includes a hearing impaired unit which has a strobe and vibrating pad. The client has now asked if I know of a "Hearing impaired" security alarm system. I don't know...

I was being lazy as I couldn't easily get both L+N in the croc clip together. I think I was lucky not to have blown-up any of the (electronic) transformers!! Thanks for your input, it's obvious really then you think about it. I = 240/259000= 1milliAmp (ish) So was the current flowing likely...

I was Insulation Resistance testing a lighting circuit yesterday. Because of ELV transformers in the circuit I only tested between Line to CPC and Neutral to CPC. I was surprised to get the same value 259Mohms for both. I know that it is quite a respectable value (for an oldish installation) but...

I would 3rd that!! I have both books. GN3 is the bible and a must. Kithcher has got great pictures and really gave me confidence that I was testing correctly!
