- Hi everyone, I’m hoping someone can help me out. I had a light in the bathroom that stopped working. I thought it was just a regular bulb fitting so I replaced the whole ceiling light and connected the same cables the same way as before to make it easier whenver I need to change the bulb. However once I switched it back on, the bathroom light and extractor fan work — but the kitchen and living room lights no longer turn on. I’ve noticed one black cable that I’m not sure where it originally connected to. I now suspect the […]
- Dear All. I replaced a Normally closed PIR some months ago and followed the same wiring pattern as the previous one – 5 wires: +ve, -ve. tamper, N & C and no problems. I am seeking to replace a second PIR but when I have opened it the wiring configuration is different +ve, -ve and tamper are the same but the two wires for N & C have been tied together and placed into N leaving C empty. Both PIRs are single items on their own separate zones and both lead back to my Scantronic 9800 control panel. Can anyone […]
- Ok Guys need a little advice here!! I've never known a bulb replacement be so complicated. We have a Fluorescent strip light in the kitchen, which will no longer come on. There is NO starter on this light. It has an electronic Ballast; I have used a multi meter and tested each end for power. One end gets a reading of 300V + and on the other end has diddly squat. I read that some tube have power at one end and not the other and the LED Tube, clearly shows which end should receive power. But still, it does […]
- Hello all from Glasgow! I'm getting a new kitchen in two weeks, will be professionally installed by a team. I've started to remove the top cupboards because I want to paint the ceiling before the new ones go up. One cupboard has a socket glued -? I can't see any screws – on top. How can I remove the socket ( just from the cupboard) please, without electrocuting myself lol? Here are pictures, Tia for any advice.
- Dear All, I have a very old (creaking) Scantronic 9800 home alarm system. A PIR has failed and so I have powered down the system and will be replacing the PIR. I thought I would change the bell box at the same time. I am looking to buy the Texecom Odyssey 3 A but online it talks about a 'tamper hold off on installation' that "only allows bona fide engineers to install" I am aware that Texecom engineers use Wintex etc so does this stop me from changing the old bell box (no make or model number I'm afraid). The […]
- I have problems when testing a Nch MOS-FET. I have learned how to do it on YouTube. However after I have touched the gate with the red pin the MOS FET does not close and I get no readings between the drain and the source. The gate threshold voltage (Vth) on this particular MOS FET ls Min 3V and Max 4.5V. I have a FLUKE 75 Multimeter. Can it be that the voltage on the pins are to low to close the MOS FET? And what voltage is it on the pins? When I think about it, this is maybe […]
- Hi there, I have a switch plate on my wall with 4 dimmer switches and 2 standard switches. On random occasions one of the dimmer switches will refuse to turn off. I'm happy to get an electrician to repair, but I want to understand the problem. It doesn't happen all the time, and not always the same dimmer switch. Generally I can turn the problem dimmer switch off the following day after multiple attempts. Each dimmer controls a maximum of 4 down-lights. I don't understand why this problem occurs intermittently not always the same dimmer mechanism. Any ideas why this […]
- So this is where i need the light in the middle, i will remove the light that is on the wall, im afraid that the switch wire will be short, the switch is on the same wall just right of the white trunking u see on the far right of the picture. this wall is plastered alrdy so not sure if i will be able to put in a new wire not sure why this image isn't embedding Gyazo – https://gyazo.com/1c4a0a8e422668644518d646a6c1f19e Gyazo – https://gyazo.com/e4b928f0a2d5d144d5234f3d598d2878
- My water purifier uses an AC-DC SMPS. The float valve in its storage tank thus operates on DC. To this water purifier I want to retrofit an AC UV sterilizer system – uses a 11w UV Lamp powered by a standalone AC choke. As soon as the float valve reaches its stop in the tank, the purifier automatically shuts off. The UV sterilizer, however, needs to be manually switched off. Is there a way I can take an output from the DC float valve for the sterilizer's AC choke? In short, I want my retrofitted UV sterilizer to also automatically […]
- Hello, I have an extension plug fitted in my conservatory, as the photo shows. It was fitted a few years ago by an electrician, and it is wired to my mains network. Recently, I had some work done in my garden, for which the workers connected heavy equipment to this plug and, shortly afterwards, the plug stopped working. The landscapers in my garden were not surprised: they told me that, as this was a spur and not a direct plug, the demand from their equipment was probably too high for it. We plugged their equipment into another socket on my […]
- I am looking for some advice. I want to add LED lights above wardrobes in the bedroom. I have installed new cable, blocked end to ceiling rose and, changed the existing single switch to a 2 gang switch. Wired existing permanent live to COM 1 and existing switched live to ceiling light to L1. Looped COM 1 to COM 2 and wired brown to L2. Whist the live at the ceiling rose is live, with a tester when switched on, the blue wire is not yet connected to enable the circuit to be completed and the light bulb turn on. […]
- Hi, Trying to get to bottom of my portable petrol generator voltage issues, engine is a Honda GX160 with a non-branded generator 240/110v outlet bolted on to it, recently started her up with a very weak current, multimeter showed only half the voltage being generated e.g 240v outlet, actual =120v and the 110 v outlet actual = 50v I don't presume to know much about portable domestic/light commercial petrol generators hence my polite request for guidance/help. I have attached several pictures of both the actual Stator assembly and Rotor etc for illustration purposes only hoping some kind knowledgeable soul will […]
- This is a DIY project. I am not an electrician. I have two LiFePO4 batteries to power the equipment on on a 12 foot plastic jon boat. One battery is 100AH and one is 10AH. The primary use of the 100AH battery is to run the trolling motor. The primary use of the 10AH battery is to run accessories, like a fish finder and lights. The primary reason for the two batteries being on separate circuits is so the trolling motor doesn't introduce electrical noise that could degrade the performance of the fish finder. For backup purposes, I would like […]
- Had new EV charger fitted 7kw, on a 40A rcbo fed with 6mm twin & earth. In use the DNO's service cable, two core lead sheathed gets hot to the touch. Like I'd estimate 70 degrees plus. Their cable seems undersized – it's smaller than the 6mm T&E! Please see pictures. Is this anything to worry about / contact DNO about?
- Hi, Our solar inverter is connected to a dedicated circuit from an RCBO in a CU in our garage. The RCBO was chosen, supplied and installed by the solar installers. The cable runs up from the CU in plastic trunking, goes through a concrete block wall to the next room, then is clipped to the wall and along a purlin at ceiling height before dropping down to the inverter in plastic conduit. Since installation last May the RCBO has tripped twice for no apparent reason. I haven't had any feedback yet from the installer, but after the first trip they […]
- Hi all, Can someone help me please. I am trying to wire up a 2 smoke alarms to the lighting circuit. I can't wire to the light fitting as there is no constant live so need to add to the switch. I have connected to the switch which gives power to the alarms but as the switch is a 2way for hallway and landing lights, the upstairs light stays on and just dims when switched off. If I disconnect the neutral the light works fine but then the alarms don't have power.
- This will be a diy, as advised from the forum! Existing installation of under cabinet lighting. Operates off switch on wall, to a transformer under the sink. Each light then has its own power feed from a junction box under the sink by the transformer. Transformer is dead. Looking for ideas or "best" path forward on replacement.
- After decoration needed to change light switch as it had stopped working. Heating engineer changed it over for us! But since it was changed over all of the lights out side and in on the ground floor work by having to have this one switch on! There is another light switch in the same room, can turn on and off from either. This one has not been touched just the one in the pictures. We stay semi rural and trying to get an electrician to come for one light switch is proving to be difficult. I have attached pictures if […]
- Hello, I recently moved into an old house (1930s) and I noticed thay the electrics seem very old. I am waiting for the report of my EICR but the electrician mentioned that it might be an asbestos backed board and also non regulation fuses. So I got a safety check done by the DNO and they said it's fine. They put some putty on top of the fuses by the looks of things. From what I've read on these forums, it seems that the DNO often do not follow their own regulations when it comes to replacing fuses? Thanks
- Hi all, Recently moved to a new house and last night, the spotlights in the kitchen randomly went to maximum brightness and the dimmer switched stopped working (i couldnt turn them off or adjust the brightness). All other lights in the house work so i turned off the light circuit for the house and back on but the same issue remained and the lights remained on. Any idea what the issue is and what needs to be done to fix it?
