Good evening all!
I was on site today relocating a consumer unit in a domestic property and got a hefty whack of a CPC...
I have never seen this much leakage in 20 years of work. It is a TNS system, the main switch was off (I got a whack of a gas bond). I am unsure what to do with the...
I had a job today and i’m back at it again tomorrow. The customer wants a new chrome fitted USB socket installed in his kitchen, but the current metal back box is 25mm.
I need to upgrade this back box to 35mm, came across this a million times, no problems at all.
With this one though there...
I have quite a bit a cat5e to run through joists under floorboards for ethernet points around the house. Can this run in the same joists as the LV cables or do you make separate holes in the joists for the ELV cables?
Cheers guys.
I have been to look at a rewire. The builders have pretty much taken the house apart and I have found the neighbours supply cables hanging above my customers ceiling.
The customers line supply cable comes into the top of the cutout and then another line supply comes out of the top and off to...
Hi everyone - Homeowner with some electrical experience, but not enough to solve this. I am insulating the garage and decided to add three outlets since there is currently only one. The most convenient place to grab power is at an outdoor garage light that is at the end of a circuit. The light...
We are having our 1930s house (recently purchased) rewired. We’ve noticed that the mains supply enters the house through our front door frame. Our electrician advised contacting the power network to recite but the prices of this look huge! Is there any workaround, such as moving the cable...
I have purchased several makes and in all case cables slip out. I still have some Old ones left and they seem much harder to co (more material) than the skanky new ones. Latest used from CEF: https://www.cef.co.uk/catalogue/products/695628
I am using a ratchet crimper that works fine with mu...
Hi,
I was walking past a block of flats yesterday and I was just wondering if the electrical lines went into the house as a whole and formed some sort of hub in the centre before branching off into their own directions or if they just entered into the walls and went straight to their...
Hello,
I'm about to start a complete house refurbishment, including rewiring and insulating between floors.
As I understand it building regs require you to drill holes through the center of joists 0.25-0.4 along the span of the joist - this is going to put my cable run ~75cm away from the...
Hi,I have fitted a timeclock throgh a contactor for some outside lights,and when I press the over ride on the time clock the lights only come on for a few seconds,then the contactor kicks,yet when I press from auto to over ride at the switch, they stay on, is this normal.I have read the...
I am currently working on wiring a hot tub. I currently have a 50a subpanel with 2 breakers(2 pole 30A and a 1 pole 20a). The wires I am using to run to the tub are THHN wires and are 10awg for the 220v, and 12awg for the 110v. The heater for the tub runs on 220v and the circulation pump, jet...
I'm a trainee electrician and I was working with a qualified electrician extending a 32A ring circuit and we were using 2.5mm single conductors (CPC was 2.5mm aswell) going through PVC conduit and then going through steel trucking.
And to connect the old ring conductors with the new extended...
My son was moving a cupboard for me & deliberately went diagonal from light switch to avoid cable. Then no bang or flash of light he just stopped & said I’ve went through a cable. After seeking advice on how to repair, we attempted to use cable crimps. Turned the power back on & not only did my...
For a lighting circuit, Do you consider it bad practice to have joint in neutral at a switch box instead of separate joint box or 3-plate ceiling rose?
Hi
This is about a design problem in an assignment.
A cable basket containing several circuits passes horizontally through an internal concrete wall (100mm) and into a ceiling void where it provides lighting throughout the building.
I'm trying to size the cables for the circuits and I'd...
I have a friend that owns a local restaurant. He's renting a building that is somewhere around 30 years old.
The building currently has a sign with lights above the signage on both sides, shining down to light up the sign. And there's a switch at the bottom of the pole that they can use to...
Hi, I’m adding a heat detector into my existing smoke detector system.
The new detector will be inspected and commissioned by an electrician, but I’m fitting it to the ceiling and running the cables to save time taken by a professional (their suggestion as they are very busy).
This is already...
Supposing I fit a metal light fitting, and I do a terrible job - and the live comes out from the terminal screw and hits the fitting, but it's well earthed - current will flow through the earth cable (hopefully) providing a circuit with less resistance than if I touch it.
When this is happens...
