Yes you can provided the original socket is not a spur and that you have a limited number of spurs from the main circuit. You can not spur off from another spur since that may abnormally load the circuit. Before you do anything you should first verify that the original socket is not a...

I personally only know of the mid-position type (but I am not a domestic CH expert) Its usually has three positions: CH ONLY - Hot Water to radiators CH+DHW - Hot Water to radiators and coil of tank DHW ONLY- Hot Water to coil of tank Some configurations do not use the mid...

This what to expect on the wires to the 3-port valve: CH only = White Wire: LIVE (230VAC) with respect to Neutral Gray Wire: LIVE (230VAC) with respect to Neutral CH + DHW = White Wire: LIVE (230VAC) with respect to Neutral Gray Wire: OFF...

laid off from primary school by the looks of it :) Don't the job centres do some sort of aptitude testing and basic comprehension testing before they spend tax payers money on these courses... I guess that's a silly question!

Your new stat needs to initiate at least three actions when calling for heat: 1) Set the three port valve to the CH position 2) Turn on the pump 3) Fire the boiler Your wiring centre should take care of all three assuming it receives a signal (230VAC) at the right terminal..... from the...

The lack of effort you have put into this post suggests to me that you are wasting your time attempting the C&G 2391 and lets hope this lack of effort saves lives by preventing you from entering the electrical industry. How did you even get past enrollment??? Please don't tell me you are...

OK if you are sure of the connections then all should be well. In any case it is always wise to inspect & test both before and after modifying. Loose connections are A-list celebrities when it comes to causing fires.

Does this mean that you have 3X 6mm t&e at the CCU? 1-incoming (from CU) 2-to oven via wall plate/direct on isolation side of CCU switch 3-to fused spur on incoming side of CCU switch That is still something that I personally would not do unless the connectors on the CCU were really...

If I have understood correctly you want to have 6mm t&e feeding a fused flex outlet then daisy chained to the oven wall plate connector. I may be wrong but I doubt you will find a 13amp flex outlet with connectors that big. I am also surprised that the original double socket accommodated...

Please can you rephrase because I'm not sure what you mean? Assuming your existing wiring is OK then you can convert a double socket to a single fused flex outlet to power your gas hob and you can plug your dryer in somewhere else but I don't see where the oven 6mm supply comes into this...

I was called out just last week to replace two downlights with a nice pendent light for that very reason. A GU10 halogen lamp blew its entire glass front over a kitchen worksurface. OK you could fit LED or florescent GU10s but that still does not solve the narrow illumination angle and LEDs...

As taylortwocities mentions, downlights are not an effective way to provide primary lighting especially in a kitchen. They are fine for accentuating features but you will need pendent or fluorescent lamps to adequately light a kitchen. If you really want downlights then you might look at...

Regarding the RCBO (32amp, 30mA) not all consumer units will accommodate an RCBO. There could be a space limitation and/or no appropriate way to connect it electrically. If your consumer unit contains two RCDs and three neutral blocks then assuming you have enough space there is a chance it...

Yes, you can place a 2.5KW UFH system on a a fused spur fused at 13amps. Connect the FCU (the new fused spur box) to the existing socket with 2.5mm2 twin+earth. before doing that, take the existing socket off, separate the wire pairs then retake your measurements at the CU. Expect to see...

One other point: When you have the ring circuit open (to add the fused spur) take your readings again at that point. You should find that the N-N/L-L/E-E pairs are open circuit. That will confirm that your spur is really "within" the ring final circuit and not off on some spur. The test...

Your meter does lack resolution but I would say the results are OK. The higher earth reading is typical and related to the ratio of cable cross sectional area. With 2.5mm cable the live/neutral conductors are 2.5mm2 and the earth(CPC) is 1.5mm2. Resulting is a ratio of approximately 1.6...

Yea, I thought that might happen. Electricians use ohmmeters that are very accurate from about 0.1 - 200ohms (usually calibrated regularly too) Most (but not all) "electrical" systems offer resistance values down in the sub 200ohm range. Most (but not all) "Electronic systems" offer...

If you are thinking of replacing the consumer unit(s) then an alternative to a delayed RCD is an RCBO (combined RCD/MCB that sits in one channel) in your case just on the garage circuit and all other circuits would be wired across dual RCDs. But you need the right consumer unit to allow for the...

Good, you are going about this in a logical manner it seems. It certainly looks as though the problem is in the garage. Keep in mind that depending upon your earthing system the tripping can be caused by a Neutral-Earth short/leakage as well as a Live-Earth short/leakage. So you need to check...

Understood.. I don't think you need to switch to the 1.9KW rating. The 2.2KW UFH will be fine and I assume you will have a local roomstat/timer? It may be best to set the timer for on-times that avoid peak usage such as breakfast/dinner times etc. From a regulations point of view what you...
