RF? Isn't it that time of the week again!? :lol:

Apologies for the photo first of all! I'm trying to calculate how much current each leg in the hypothetical ring circuit is carrying. I'm sure I've seen an example on how to do it here some where. Can someone point me in the right direction, or run through the calculation for me please...

Greetings all. Can someone help me understand how a patch panel works. This one for example. If you run one cat5 from each port to an outlet. I understand if you plug your internet rj45 into, for example, port 1, then the net will be distributed to outlet 1. How would you get...

Hi guys, Lectrician posted some pics in this thread some time ago, of how to terminate split concentric cable. They have been removed as I'm sure you can see! Can anyone either repost, or tell me where I can find them. Thank-you. :D

Hypothetically. If you used electricity as the only source of fuel in your house, could it compete with the general gas and electricity used by most. For example, if you used an electric boiler to supply wet underfloor heating, used lots of energy efficient lighting. Perhaps ran a solar...

Greetings. My friend just rang me. I don't know why! She has no hot water coming through the taps at all. It was fine this morning. She has an Immersion heater, and says the tank has water in it and is warm. I suggested the pump may be gone but would appreciate some pro advice...

Greetings builders. I am about to build a small canopy at an old peoples home for a couple of them to huddle under whilst smoking a fag. It's more of a favor than a job as I am a spark by trade. :? I intend to construct a timber frame, thunderbolt it to the wall, then stick a sheet of...

Hi all, I have been offered a small job by neighbours for the weekend. Having only carried out a few jobs before, I'm slightly nervous yet confident! It consists of upgrading main bonding and installing two RCD sockets in their 'shed' for washing machine/tumble drier. The shed is...

Greetings All! Why would you use this in a consumer unit rather than a MCB? :?

Do these exist, and if so, does anyone know where i can get them from? I want to make up a lead consisting of a length of flex with a croc clip at each end. Help needed.

Following on from Plugwash's post in the 'Loft Electrics thread, how do you terminate split concentric cable? I've never even seen it! (Aplogies if this is a stupid question!) Oh yeh, and when is it appropriate to use this cable? Also having looked at the pictures on the TLC website...

Rewire of an upstairs lighting circuit using cable of the same current carrying capacity and following the same route. Connecting to existing 6A MCB. Is this notifiable? Elec Guide to BR seems to suggest not, although it's not toatlly clear. Can someone give a definitive answer please...

Hi all, i am a C&G2330 student. I went to meet a registered spark today quoting to change my mums CU. It is TNS with a 10mm main earth emerging from some insulation tape on the supply cable. The tails are also smaller than 25mm (not sure what size). The spark said he can only upgrade the...
