Hello all.
So I am sure the expertise on this forum will be able to decode this very easily. But it has completely baffled me. I'm in training so forgive the ignorance.
Doing a bit of dead testing on a lighting circuit downstairs. Came across this at a light fitting.
Appears that the colours...
Good evening all, I’m currently part way through my apprenticeship and we are working on IB, IN, IZ and IT and volt drop today. And it got me thinking I have seen a circumstance at work, where:
A shower has been wired in 10mm T+E on a 40A breaker. But then from the shower isolator switch a 2.5mm...
I am working on a RV Park and I have a question.
I plan on installing 4/0 quadraplex AL URD cable to 10 pedestals on a 200 amp circuit and downsizing the wire to 2/0 Quadraplex AL URD cable for the last 4 pedestals. I have calculated voltage drop and everything is below 4%. Table 310.16 says...
I have had my kitchen rewired and plastered. I have had a 6mm t+e on a dedicated 32a circuit for a 60cm electric cooker. In hindsight, had i known at the time, i would have asked for a10mm cable to future proof the installation. The cables run from the consumer unit in the attached garage, into...
I am a retired electrician and I've been out of the game for a while. My son asked me a question the other day and I wasn't too sure how to answer it so thought you lot might.
He wants to use rails to supply 5 modules, each module will have 40 small actuators that operate at 24VDC at 0.9As...
Hi, recently moved into 30 year old home. We were renovating it for a few months and didn't notice this issue. 3-4 times over last month the power has gone out to the entire home, without flipping any circuits. When we've been home for it (twice) it has only lasted a few seconds. I'm yet to ask...
As I've mainly done site work and moved into domestic recently, I'm a bit rusty on stuff like this, but if I'm adding a loft PIV unit to an existing lighting circuit via an unswitched fused spur, if the lighting circuit has no RCD protection am I allowed to install it?
Same question for if...
DIY query
Have narrowed down the source of an occasional trip to one light circuit which is a varilight v-pro master dimmer slave set up.
This is one of 5 LED, low total wattage light circuits connected to one 6A RCBO breaker (so the issue could be a short or a ground leak). Zero problems...
Please advise what I should test / check next.
My usual qualified electrician who did all of the work here is in Ireland for 4 weeks and not contactable. I need to fix this asap. Ring final circuit tripping. I am not clueless and I have some test gear. Can fully isolate the supply with an...
Hi everyone. The title should sound crazy enough, but it's what happening in my 72-years old home we've purchased 2 years ago.
I found the crazy wiring when I was just troubleshooting on a lighting which has been flickering, and finally completely failed recently. I recognized the lighting is...
Hi,
Just been scratching my head about this one and wonder if I've missed anything.
A few weeks ago I installed a new circuit for a 3kw oven and a 950W microwave. Ran the circuit in 6mm T&E clipped direct on a 40A RCBO.
Customer has reported that on maybe three or four occasions the RCBO...
Hi,
So I'm trying to understand what's going on with my off-peak electricity supply, as something's wrong with it and I'm trying to determine if it's the responsibility of my energy supplier or I need to get an electrician out to take a look.
Here are some pics:
I live in a flat...
Hi everyone.
I should start by saying I'm not sure I'm in the right place here (this isn't a householder issue - I'm making a Ghostbusters backpack for my son!), and that I have no knowledge at all of electrical circuits.
I have a simple circuit with 3aaa batteries powering a string of static...
Hi guys
I have some industrial lighting circuits to wire in a workshop and was after some fresh ideas/suggestions as to how i could best do this.
Have done a few of these before and in the past i have sometimes run radials in SWA cable to single gang socket outlets. The High Bay LED lighting...
We have one room that seems to have lost most of its power last night. One of the outlets in the rooms has a power strip plugged in that powers the tv and video games, but we flip it off when not in use to save power. Last night, when I flipped the power strip on, the entire room lost power, but...
Hi everyone, 1st post here. I'm a DIYer looking for some advise please. I've got a blender/mixer from India which has decided to pack up. I've narrowed the problem down to a circuit breaker (thermal overload protection switch) I'm not able to find a match on Google or on screwfix, does anybody...
Hi
Customer has an extractor fan that’s inside the shower cubicle high up on the wall. The extractor fan has no form of isolation and is wired into the socket circuit not the lighting circuit (I have never seen this set up before) and hasn’t been fused down. So because of the way the extractor...
Send your layout to PCBWay for instant production with just one click.
Have you ever thought that when you complete the design on KiCad, you can place an order on pcbway with just one click?
Now this idea is finally achieved.
When you click PCBWay Plug-in button on Kicad, we will export...
Hi all
EICR today on a ground floor flat .. 1 issue ..
At the consumer unit there was a 1mm core with its yellow (sleeved brown) in a 20A radial circuit mcb ( socket circuit ) and the blue in with its neutral.
When I disconnected it I found it was attached elsewhere to this circuit .. not in a...
