Hi guys, I had to carry out some alterations to a domestic installation the other day and was pleasantly surprised when having to run a new circuit how neat the CU was. It had 75mm metal trunking installed to the CU with bass bushes installed. A lot of effort had gone in to it to keep it neat...
I have 3 circuits (microwave, disposal, and dishwasher) entering a metal box where the THHN wire will be spliced to Romex.
I spent half an hour reading 2020 NEC Article 250 but didn't see multiple circuits specifically addressed.
To ground the box do I just need to pigtail off of one circuit's...
Looking to put in some dado style trunking for a few power circuits and some Ethernet sockets, ideally metal type from a fire/EMC point of view.
I had though of using the Marshall-Tufflex "System 130" (or maybe the bigger 170) steel system but wondered if the folks on here have any better...
Hi guys,
I hope everyone is well.
So to detail my experience, I had a loose wire behind my electric cooker mains plug, so I tested the plug after sorting the wire forgot to turn off the mains at the box and yes as you can guess as I went to push the socket into the wall to screw in, two...
Hi, I recently bought a metal halide fitting but I have no idea how to tell if its a pulse or probe start unit.
I have what I believe are both types of bulb and the fitting will start both, would that indicate its a pulse start?
With the bulb which I believe is a pulse start bulb (has just a...
Last year I had a large cast-iron balcony constructed with steps down into my garden. The balcony is bolted into the walls and also into the pavement where it meets the garden. Is there a requirement to earth this? If so, should it be a separate 10mm CPC direct to the CU or could I link it to...
Hi,
I'm taking swa out of the shed and fitting it along a metal fence with metal fixing band. Swa goes into a wiska box then flex from the box to a light that's bolted to the metal fence. Circuit is protected by rcd.
Does the fence need to be bonded at all? I'm guessing it's an extraneous...
EICR on an empty property this morning, potential buyer has instructed, few bad points but overall not to bad, and then this.....16a wylex plug in mcb-2.5 t&e- 32a 10ma Crabtree rccb then runs 8 metres in conduit (broken in places) then goes underground for another 20 metres to feed a db in a...
I’m looking to swap the plastic switches & sockets in our house to metal.
Ive removed the plastic faceplate, and can see that there are a couple of earth wires in the back box, which terminate into a choc box. I assume the builders left them like this in the event people swapped to metal like...
I can't get my boards as artistic as some of the YouTube sparks but came across this absolute shambles today... I know there's cowboys in all walks of life but do any other trades suffer so much with unskilled people charging money to do skilled work? (and getting away with it)
I am planning a job in Bath for an EV Charger on a Grade 1 listed building.
Have a long cable run at height, planning dept have raised issues with cable cleats! feel they are a bit chunky and would prefer something with a less chunky profile!! given they are nearly 2 and half stories up from...
Hi, had a rewire done, sparky didn't replace some of the metal back boxes, just run new cables into them, I don't have a problem, taking them out would have caused the plasterboard to get damaged, but mrs thinks they should have been done. Seems pointless, they are metal, new rubber grommet...
Following on from this saga: SWA questions, doubting electrician - https://www.electriciansforums.net/threads/swa-questions-doubting-electrician.180536/page-2
I had an electrician out to quote to rectify the problems yesterday after dealing with the tripping issue myself. I have now been told...
So I've got incoming mains splitting (forking) off into 3 light fittings. They are HID metal halide lamps. The middle one (thats not working) is 70W, and the other 2 are 150W. I've replaced the control gear and bulb. It still just flickers blue and doesnt actaully start. It also buzzes at the...
So I'm trying to run this 400w HID light in Japan (which has 100v output) but the ballast for the light is rated for 120v-240v.
I want to know if the light will still operate, albeit at lower output, or if there is risk of damaging the light.
Hello there
I bought a vintage smoked glass shade chandelier pendant ceiling light and wired it up ok (well the bulb didn't blow) but took it back down because the brass thingy wouldn't do all the way up on my existing ceiling rose.Can i just wire up the metal ceiling light holder...
Hi everyone!
I am an industrial designer working from Israel, currently working on a product that will be installed in american homes and needs to fit into a one-gang box.
I'm having trouble figuring out how common are the metal boxes out of all the home-installed electricity box...
I have 5 x 6m metal posts sticking out of the ground used for 200w floodlights to light up a manege.
This is a domestic stables. The posts test as 35ohms to earth. The installation is TNCS and has 30mA RCD protection on all circuits.
The floodlight will be earthed and in doing so the post will...
Hi all
Recently my company (I'm just an employee) moved into a new unit and have installed some shelving, the BigDug kind.
We've had plug sockets located above (2) each unit to provide power. This was done by the electrician so that's all good.
I need a plug socket on each shelf (5 in total)...
