Hi all!
I have a light fitting with 3 lights on it in a row. The middle one burnt out right away when I connected it.
Then I started another thread prior to this one which solved some wiring questions. It's now all connected ok. When I replaced the middle light after all of this was done and I...
I am having some trouble with replacing a lighting fixture. I have done many throughout the house without issue, but this one is perplexing me. It is a light with two switches. When I took the light down, I was in a hurry but I swear both the black and white wires on the fixture were wired to...
Hello all, I recently was asked to quote a three phase motor install within a pallet factory. To be honest, I was somewhat stumped in how to attack it as the sheer size and the control cabinet was gigantic. Although I'm mainly a domestic, commercial spark, this was somewhat out of my league. The...
Was testing a EV charge point today and noticed the internal RCD was TP device with only a single phase supply and load in use (L1).
There was 245V either side of the RCD but the test button didn't function.!!
Is it possible the test button is fed from one of the phases that is not used...
Hello,
A few years ago I had my house rewired before putting up new drywall. I had a three way installed to control the lights in our mudroom, one at the exterior door and one in the kitchen. This is currently not working correctly and I am trying to understand why.
The wall box at the...
I'm refurbishing my own workshops and fitting a new central three phase compressor and three phase dust extractor.
Both these appliances will be controlled by remote START/STOP switches, next to multiple compressed air and vacuum points, which may be in different buildings.
For future-proofing...
So looking at a system that utilises a couple of sizable UPS unit to supply various equipment through a site. The UPS is static with 3 phase output, both units have an input switchboard and output switchboard with a castell interlock so that the bypass can not be switched in unless the UPs...
I have a workshop in a remote location which I rent out. The incoming supply is 3 x 16A three phase on 180m of 16mm SWA.
An upcoming customer has a machine which needs a 32A single phase supply. (Actual load about 25A.)
The energy is there, but it's split across the three phases. Is there some...
Has anyone had this issue before ? Was working on a three phase board, when I took the cover off I noticed a black spot on one of the rcbo’s. it happened to be smouldering and started to catch a light. I noticed another rcbo smouldering too. I instantly turned off the main switch as one of the...
Working on an electrical drawing and wondering if I can split a single 12/3 wire (blue&red together) into three 12/2 wires (2 blue & 1 red separated) using pigtails at an outlet so that the wires can travel in three separate directions as in fig 1? The wires attach in pigtails as represented in...
Thoughts of experts welcome. The first smart meter installer walked away as he wasn't three-phase qualified but i'm wondering whether we should get Western Power out beforehand or whether any other work would be recommended. Not sure what the supply box on the right is feeding and I think Noah...
Hi, I need to refit a timed extract fan, there are three connections on the fan body, clearly marked, fine with that, but the supply cable from the ceiling is one cable only, one brown and one blue, the bare earth wire was just bent out of the way. It was working fine before disconnection. There...
Hello - I hope someone is able to help. I have three light switches (2 x 2-way, one with a dimmer, and an intermediate switch). I seem to have trouble with my intermediate switch. Both the 2-way switches/dimmer work as expected. But if I switch the intermediate, the light goes on and neither of...
I am thinking of having a car lift (that uses three phase supply) installed in my house, my house is single phase, what are my options?, what would be involved?
Outage of main three phase primary switch box for one of three buildings on commercial site. The building houses around 30 commercial units. Switched back on the main switch, power restored. Except for one unit. All units supplied through the secondary sub switch box. Large MCCB MEM type.
