Hello People,
I have a 10kva site transformer with a 32a 2P+E plug with a 3G4mm2 H05VV-F(yellow) as input.
A temporary DB will feed him and a socket with the same characteristics will be provided but not sure if I still need to keep the same cable colour( DB is on 230v).
Thank you
I recently had some landscape lighting put in and wanted to hook up the transformers to a smart plug so I can control them with my phone and have them on a timer etc. Currently, as setup by the electrician, the two transformers are in a double adapter plugged into a normal wall socket and it...
Hi, I'm hoping someone can offer me some advice.
The transformer for the lights in our bathroom has gone and I'm looking to source a replacement. However I can't find a like-for-like one to replace it, so looking for some suggestions for which one to get. The current one is a ring DET-200...

Hello there, I brought a 5000W step up/down transformer with me for my appliances when I moved back from the US earlier this year. I'm living in an old house, don't think the wiring is up to much, and from the beginning the transformer would trip the circuit board switch, though I could just...
Had a quote today at a new build where they've not bothered to put any facility for a doorbell.
Customer has purchased a Ring Wireless Pro, which comes with it's own 24VAC DIN rail mounted transformer.
Given the location of the CU, it is not the simplest path for a cable run, so looking at...

First post, DIY.
I harvested this heavy transformer from an instrument that we took out of commission.
I live in a 220v country and I want to know if I can use this safely to run 120v tools (like routers etc).
1. It states 2kv. Is this ~2000 or ~4000 watts? (i.e. do I multiply by 120 or...
I currently have this,
Primary inductance on an AC transformer will determine the magnetizing current on the unit. Usually inductance is relatively high so the magnetizing current can be as equally low. This inductance can be seen as part of the magnetizing current; however, it will not be seen...
An interesting sign has appeared on a local DNO distribution transformer, earths missing from Transformer and HV switch. Is this what is meant by a hot site?
Hi, wondered if anyone could help with this. We have purchased a 12vdc caravan pump to use in our food trailer. They are designed to run off a leisure battery but we have a generator and would like to run it off a standard 3 pin 240v plug.
What would be the best transformer to use?
Attached is...
On the other side it is the power transformer. Trying to figure out why my lg 55lf6000 screen keeps blinking in 1.5 second intervals. So I’m wondering if that spot looks burnt and hoping it is the cause. It’s just I’m wondering if that spot is normal.
I have 12 x 40w halogen downlighters in our kitchen ceiling which I want to replace with 4w LED equivalent. Can they be a straight swap? Will there be an issue with the transformer/voltage?
The light switch is standard type. If I wanted to upgrade the switch to a dimmer type (and the new LED...
Hello everyone,
when we talk about power transformers and their cooling we have fans and oil pumps. As I can realize, the transformer is at first cooled by fans and if the fans are not enough, the pumps starts. Am I right? Now, is there two pumps for both direction? One for drawing the warm oil...
Hi all,
I hope I’m posting this in the right place, please give me a kick if I’m not. :) I have attached two photographs. Can anyone please tell me what transformer I need to buy to be able to use this item? I have seen transformers for sale in various places, most of them are for 120 to 240...
For those of you who work with onsite MV-LV transformers, does anyone know the line to earth ohm value of a transformer? I'd like to include that in the loop impedance path. Similarly when stepping down LV to LV.
