Hi,
I have purchased a Ring Video Doorbell in the UK, and am looking to install it. I live in a New build property and the transformer to the Chime is within the Chime unit. Looking at it the wires come through slightly differently to the installation video, and I'm trying to confirm how I...
Older Japanese made microwave transformer has 3 connector terminals on the primary coil. Haven't seen that before, any help appreciated. It's a dpc-240.
Hi guys is there any regulations regarding 110v centre tapped transformer transformer circuits being used outside (rcd protected) also if the transformer states 3000Va but a continuous rating of 1650Va am I right in thinking it can only carry 15amps before the transformer overloads?
Hi vent-axia Svara bathroom fan going in zone 1, vent-axia PSU centra selv lo-carbon (12v transforme) question = how far can the PSU be from the fan, i would like it about 1.5 meters from the fan (cable length) or must it be as close as possible (in the loft) to the fan 1.5mm twin+earth cable...
Hi,
First post here - so be kind!
I'm looking for some advice about the best option for a bathroom LED strip installation.
I'm based in Spain, but British. I'm not a qualified electrician, but have done small electrical projects in the past, such as installing lights and sockets in an...
Hi all,
I converting a van to a camper and wanted lights for underneath the kitchen cabinet.
I purchased this led light strip for Home Depot (https://www.homedepot.com/p/Commerc...-RGB-LED-Strip-Light-Kit-DT8800-16F/312590609). The first one I bought with USB connection just wasn't bright...
Hi
I have a Transformer, that needs a rewire on a Secondary windings, the wire that was on it, was a muti-core wire 9 strands, (0.06mm x 9) ( each strand enameled ), soldered together at each end, and laid on top of the primary winding with 175 turns, with a copper tape between the primary and...
Hello
Have a ring doorbell which is powered from the mains using the ring branded transformer that came with the unit.
Its been working well for about 2 months since it was installed by an electrician and then just failed last week and appears as though no power is reaching it.
I used a...
I'm connecting three phase step down auto transformer. 400V input and 230V output. It's to supply a piece of equipment brought over from America and the load won't be balanced.
My question is, is the star point common for both the line and load side neutral connections? I'm leaning towards yes...
Hi,
First time posting on here so apologies if I'm missing any basic information, but hopefully someone can help me as an amateur DIY-er and definitely not electrically knowledgeable. I suspect the best approach would be to get in a professional to help, which I'll likely do but interested in...
It took me ages to find a suitable transformer that didn't cost several limbs, and while my load at the moment is well within it's rating, I'm curious as to what power rating I can assume for this setup. It's not too important because the total load I have planned on 240V is only 160W, so at...
Currently I have 4 small low voltage transformers connected to 4 circuits of low voltage yard lights. They are under my deck, and I turn then on and off using switches above the deck.
I want to consolidate those transformers into one transformer...
I have a quick query. I have a bathroom mirror with built in shaver socket and isolating transformer. However, it is not switched and is permanently on and as it is in an en-suite the humming/buzzing noise of the transformer is amplified from within the mirror casing and is annoying. I am...
Hi got a 10kva transformer that keeps tripping. Im told its about 20 year old. Its fed off a type C 32 amp breaker. Single phase. Did continuity test between windings and all ok. Secondary has a centre tap so is that why I would get continuity between phase and earth? Not worked with much...
Hi All,
So i was asked to look at at large 3 phase to 120V transformer around 85kVA - it was tripping the MCB instantly (it never used to)
I insulation resistance tested the primary windings to earth - >2000ohms
I continuity tested the windings and got 0.46 ohms per winding, they were all...
I hoped someone might advise please: I'm replacing my ancient ( probably 40+ yrs old ) door bell transformer with a British General unit mounted in a Wylex housing, fed via a switched fused spur. The previous unit had a switch only, it was fused at the consumer unit connected into a lighting...
I have a Ring Doorbell which has no Chime, but which is trickle charged via a wall-mounted BG DIN Rail transformer in a Hagar casing which diverts power from a socket cable. Firstly I have a electric check coming up and I wanted to know if this was safe or is it likely to be picked up in the...
Installing a wall mounted transformer.
Single phase with 2 x 16 amp sockets
Input connections are 240v 220v 0v 10v
Output/secondary side 55v 0v 55v
Whay would the connections regarding the input/primary side live neutral earth.
The 10v is throwing me off
Installing a Ring doorbell - followed all the instructions and the ring is not powering on. I believe the issue might be the transformer in the chime box isn't powerful enough for the job. Ideally I could just replace the transformer pictured below with a newer unit which has the required specs...
