Must be gold plated version...

Thanks, yes I am aware of that point. I fit them to maintain the integrity of 30/90 minute fire rated ceilings. I fit the metal joist covers in an aid to prevent the top of the unit getting covered with insulation. actually I try to talk people out of them altogether unless they are to...

Evenrob, just a note on your RCD. The RCD is not in any way connected to earth and "knows nothing" about the earth circuit. A modern RCD simply looks to see if there is a difference in current flow between LIVE and NEUTRAL conductors. It assumes that if there is a difference then the...

Evanrob, the earth rod you planted is not really isolated. It forms a high resistance path back to the sub-station transformer within a few miles of your house where the centre tap of a star-wound xformer is connected to earth (it also joins many other parallel paths too) The main point...

Yep, just confirmed that on my box...

I have a V+Box (Scientific Atlanta) connected to TV via HDMI at the moment. Just going to see if the RF out works (outputs the selected channel)

You can take a coax cable from the connector on the back of the box which is marked as one of the following: TO TV RF OUT TV You could also use the SCART or HDMI outputs (assuming your tv has those connections) but you would probably need to buy the connectors and cable and build it...

Not sure I fully understand what you want to do so a few questions: 1) You have added an additional lighting point to an existing lighting circuit in the same room? 2) So you now have two (or more) lights in that room that come on at the same time and operated by a single switch? 3)...

Now you dragging back memories of a simpler time!! I do indeed remember that and attempting to restore valves (especially the PL509 line output pentode) by getting out the "rheostat" and super-heating the filaments in a feeble attempt "clean off" the cathode :) It does sound like the 56.5...

I saw the video too, great shame! Must admit it did look like they were getting shocks from the ground. Induced VF into any heart (horse or human) only takes a small amount of current flow in the right place at the right time (it can sometimes depend on heart rate and which part of the...

Assuming it has the correct IP rating then you can provided you use the correct (approved) driver and it is wired in full compliance with current electrical regulations for ELV/SELV/PELV But determining that and installing it is a job for a competent registered electrician...

I used to repair TVs back in the mid/late 70s.... Quite often came across early 60s sets that had a live chassis and consequently a live screen on the ariel connector and cable when it was plugged in! It was common practice to use the metal chassis as a "common" on old TVs/Radios Some...

Yes those 50watt/35Watt halogen downlights generate huge amounts of heat. I have seen scorched timbers several times when pulling out old downlights. The fire rated ones still need careful attention when siting them and I use metal joist covers where possible to keep loft insulation well away...

Did you have any luck with EON? The only theory (and I stress theory only) I can think of is that your original earthing system had quite a high impedence (similat to resistance) and the repair accross the street meant replacing a section of cable that contributed to that high impedance. Now...

Just googled energy let-through and I see it is I2t. I guess that it refers to I2t over the entire period from fault current intiation to final disconnection time (melting time of fuse link) I imagine the fuse link starts its "melting process" on the first fault cycle and stores heat from...

Hi Ya'll... I read an interesting post on here a few days ago but can't find it now!! Did not get a chance to read it all but energy let-through came up in the conversation/debate. The main topic may have been about regs compliance of some sub-mains. I was going to join the debate at the time...

Also what length of cable from transformer/driver to lamp? Voltage drop will be high on 12 volt or other ELV circuits...

LV (assuming you mean Low Voltage) can be upto 1000 volts. Assuming you mean SELV or PELV at perhaps 12 volts? You don't mention the voltage or the wattage of the lamp(s) If you are talking about a 230VAC primary /12 secondary transformer/driver then the following comparison may...

I think he means that the number of spurs should not exceed the number of sockets wired directly to the ring. Correct and apologies for my lack of clarity in that statement.
