I'm carrying out an online course to gain my qld electrical licence.
Been a good while since calculating cable length using equations and regs books.
Can anyone guide me to the correct equations please
Thanks in advance
I came across some cable today I haven't seen before.
It has some sort of tough, inflexible pvc type sheathing (definitely not rubber). It's quite a light silvery grey and more oval shaped than modern flat T&E.
Probably tinned copper conductors, but maybe even...
The image is connected to the plug on my Airlux dishwasher. It's blows now. I can't find it on line to get it for my electrician. If possible I would [refer to replace this before getting new dishwasher.
I have seen a replacement on Espares but it's not precisely the same.
I have been asked by my brother to take a spur from the ring main to a summer house from the house (7m) T&E. BUT I have since found out that the house has not be rewired for about 40yrs. Is it safe to connect a 2019 T&E to an older Ring main. Consumer main fuse 45A
So someone has asked suggestions as how to upgrade lights in a small narrow kitchen in a new build. The kitchen has a low ceiling - albeit subjectively (the guy is 6'7" and at the moment only blocks the light from the one pendant where ever he is in the room). Obvious choice would have been...
Can I ask some advice on what to bury please?
This is the the front of my house in plan view. House at the bottom. Porch at the bottom left. Driveway at the top. There's a fence between the driveway and the lawn. The incoming electricity supply runs underground down the left hand side of...

We’ve got to get couple of SWA from DB and up the garden: 1x16mm 3core and 1x2.5mm 12core.

Currently working on a job where the client was concerned about the swimming pool heat pump tripping the mcb (the mcb is more than adequate for the job).
The heat pump 4kw and pool pump 1.2kw were drawing 27/28 amps with only 197 volts measured at the pump room. It’s about a 60 meter run.
Hi all - have discovered a damaged cable in the loft - seems to be from the 1st Floor Lights Ring Circuit. Have cut the cable and reconnected it with Wago Connectors - see pics (yes i have switched off electricity and tested the cable was dead before cutting). This particular cable has 4 cables...
Hey looking for a roughy idea of how old this cable is,
It’s a rubbery cable some of it is twin and earth other is just 2 core red and black and the 3 core is red, yellow and blue. It looks like the conductor is tinned copper and it’s about 3 strands to what looks like 1.5mm of its imperial...
I've been asked to supply power to the middle of an office floor to supply the table with power, only a small office but they don't want trip hazards but the don't want floor boxes so to keep there costs down for them instead of it being permanent in case they move I thought of chasing...
After some advice please..... we've been using just basic off the shelf CAT6 from our electrical wholesaler for a while now.
We're finding it twists easily, haven't had any problems yet.... but you never know! And we seem to be installing more and more of it on every job now.
Hi guys, hopefully somebody can help. I have some driveway lamp posts with the armoured cable installed though the middle of the concrete pad. Unfortunately whoever installed this did a rubbish job as the concrete is not level and the posts look awful. I was going to cut the cable and dig out...
What is common practice when hooking Armoured cable to a weather head. Do I need a aluminum weather head or is a threaded PVC one ok? Do I use a weather head with threads so my teck connector can screw straight in.....do I need ground bushings at both ends?
Any advice is appreciated.
Been asked to do an eicr on a flat above a shop.
Tails are run in concentric cable from isolator switch by the meter, to the main switch in fuseboard.
Never run into this before so not if this is still deemed acceptable or not? Any advice, reg numbers?
Thanks in advance.
Im very new to this forum so thanks for hearing me out.
I have an led light that is waterproof. The issue im having is that the cable is not long enough for its purpose. I needed some help or advice as to how i could find a cable attachment to increase its length.. i have attached pics...
I am converting from overhead too underground service to my house. This involved moving the meter about 11 feet down a wall from its current location. The old meter base sits directly outside of the electric panel. So, at the new meter base, I plan to penetrate the exterior wall...
Hi - working on a new kitchen today and while stripping out some cable I noticed a damaged section, pic below. I had a good look about and no external heat sources nearby, so I can’t blame the central heating pipes. The conductors’ insulation doesn’t seem to be heat damaged, maybe it’s tougher...
I have a block of 9 flats 3 floors ,ground ,1st & 2nd.6" cable tray going from top to bottom x2 .LV and HV.The contracts manager is insisting on the tray stopping between floors and a 4" pipe with a fire collar around it to go through the flooor.Is this correct.
I was asked a question today if it would be possible to use an existing cable that was previously installed to supply a shower which has been taken out (6mm T+E) to feed a light in the loft. Initially I said no it wasn’t good practice to do this, but now I’m thinking as-long as the MCB is...
I have limited construction background, specifically residential framing & roofing. I have been on numerous job sites (and would NEVER attempt electrical work or repair of any kind) but am curious what kind of curly electrical cable this is and why it is used. I have not ever seen this sort of...
I think I may be going mad...job I was at today there was a strip light needing replaced, were 3 feeds & neutrals and a feed & switch wire at it. Was sure I marked everything ok but as there are ceiling panels going on before the light goes back on I thought I’d do a quick check, turned light...
To start, I have to say that I'm a very beginner with electrical stuff, I'm working in IT and today I face a challenge that I can not resolve by myself.
although I work in IT, my boss ask me to find a way to weld a specific cable, for a specific problem.
I'm studying a protocol...
Contemplating getting a set of THESE (in both 1.5mm-2.5mm and 4mm-6mm) for marking up circuits inside domestic CUs.
Anyone had any experience using them? Do they stay on? Are they pointless? Can they be found cheaper anywhere (CEF sell them in packs of 3000, at £80 a pack...
Hi to all first please may I point out that I am an avid DIY person but know my limits. I would like to know from all you very experienced people out there what size of Armoured cable to use to put power to my steel container, i am in the process of turning it into a work space and a Sauna I...

Would like recommendations on what type of cable you guys would run for outdoor lights which are covered by a porch ceiling. ( if that makes sense )
The cable would be clipped direct.
Would you guys recommend pond wire which is water proof or SWA or even normal flex wire ??
I was tracing some electrical cabling last night and noticed a ~6" section of 2.5 T&E cable that appears to have been subject to heat damage and the plastic has started to melt. It's about 1m away from the CU in the garage and connected to a 32amp MCB. It's a radial circuit that powers a small...
I'm planning to put an RCD socket on my balcony through the wall, which would mean ~1m of the cable will be outdoors (The other end would be plugged in a socket inside).
Now I have the perfect length cable lying around (PK TSE HAR H05VV-F 3x1.5 PX95), however after some research I found...
Unfortunately last weekend while digging up tree stumps I managed to go through the power cable for the local scout hut. SSE are now billing me £330 for fixing it! However a neighbor thought I might be able to argue it as it's only 200mm below the surface. As it was installed with the scout hut...
I purchased a bench polisher which looks to have come from China. It says its 220v single phase and should work fine in the UK. The power cable has 4 wires in it so I'm confused how to wire a standard UK plug. I have attached a photo of the cable.
Any advice would be much appreciated.
