swa

Hi Folks, I moved into a house that had an existing SWA cable (20mm, 4-core) going from the house CU (RCD) up the garden to a smaller CU in a brick shed (about 80 feet away). When the house clearance people were clearing the garden they thought it wise to burn all the old weeds and ended up...

I`m planning to build a summerhouse/workshop down the garden. Cable length would be around 45/50mt. Mostly power used 13A and maybe some mig welder 16A Do I need to get a 3 core cable or 2 core would be fine and Earth can be sorted out locally? What would be the ideal size without spending a...

Hi, I need to put a new supply to garage as old supply is a 2.5mm T+E spur off of ring main which runs overhead outside! Is it standard to a) run the SWA all the way from the house CU all the way to the CU in the garage in one continuous run or b) run T+E from the house CU to a junction box...

Not sure on the regs for this, if anyone could enlighten me. What are the rules on running 2 single phase circuits in 1 SWA cable. I've got a lenght of 10mm 5 core cable and want to run 2 circuits in it out to the outbuilding. What would this do to current carrying capacity ratings? Just...

Hi I have reviewed some previous posts but I am not sure of the size of SWA cable to use for a garage and workshop. I am only planning to put the cable under the floor before some laminate gets laid - I am yet to get planning permission for the garage - but thought I would save an awkward job...

Hi all, I'm having a car charger installed. The organisational process is complex - I talk to the project co-ordinator, who talks to the technical manager, who talks to the installing company. The project co-ordinator has raised the issue that the installers might need to do some...

I need to run a length of SWA along the back wall of the house. The route crosses the back door. It won't be very pretty to go up and over it. However, there is a recessed gap between the door threshold and the patio slab. Obviously it's in an area of foot traffic, but it would be visible and...

Hello, I'm in the process of planning a small garden office build. I'll build the office but pay an electrician to install the electrics. However I just want to understand the potential extent of electrical works required. I currently have a BG dual rcd board (I know BG isn't great but it...

Hi Guys, going to be building up to DPC for my project this week. There will be 2 bridges for water and electric supplies to run under the blocks... what size/rating lintel will i need (assumng i need 4 lintels also)? Thanks

Hi Guys, Im just running my utilites to my new outbuilding (still waiting to be built up to DPC). I had to run utiities first due to access etc. Is it ok if i run the swa beneath the dpc with a lintel and up through the concrete floor once its poured etc? DO i use a hockey stick to bend it in...

Hi Just after a bit of info about garden power, and don’t worry I will not be doing any of the connections myself and will be getting an electrician to do the work as I understand it needs to be notified to relevant organisations (part P). What I’m looking at doing-at the most we will want to...

Hi all, I need to replace the old fuse box in the garage with a CU and at the same time install a load balancing a fast charge outlet for electric vehicle. Current installation has a sub panel in the house (40A) with type B MCBs: 20A for kitchen sockets and 32A for the garage supply. Main board...

Wondering if I could get some advice from you sparky’s please. House consumer unit connects to another consumer unit for the kitchen. Kitchen sub consumer has electric oven, induction hob, hood, lights and sockets connected. The connection for this secondary consumer unit is 16mm 3 core...

Hi all, Hoping you can offer a novice some advice. We've had the house re-wired with a new fuse box with RCBOs. Our electrician left the build a while ago and has sadly passed away since. Before he left he didn't finish connecting up the SWA cable running to the shed, so I've done it using some...

Hi there, I have a 6mm 3 core SWA running to the garage and need to sleeve both the black cable (earth I think) and grey (neutral I think). The wires look like being 4mm in diameter so am right in simply saying I need to buy 5-6mm sleeves? Cheers

Hi, I'm having a log cabin built at the bottom of my garden. It was originally intended to be for dual use as a summer house and for extra storage but I'm now thinking that we could use it as a gym and with that in mind, it would be great to be able to have a shower and perhaps a WC/washroom as...

Hi I am looking to get an electrician to connect power to a cabin in my garden which is located 60 meters away from the house. Could any one tell me what SWA cable ( 2,3,4 core? etc and what thickness? 6mm 10mm) I would need to supply it please? The cabin will have the following things that...

Hi We've recently fitted a "Y" branch joint to the SWA cable that feeds our garage to run some power to another out building, however we're now experiencing tripping of the RCCB on out circuit board which can only be cured by the garage MCB being turned off. Having had a search on here one...
