Hello,
I have a hypothetical question (I'm an electrical engineer) to better understand RCBOs and how they are used in the USA. Let's say I would like to install RCBOs (or maybe just RCCBs) in my home to protect against residual currents. I am in the USA so my home has split-phase (two phases...
I have a sub panel about 75ft from my house attached to my shed that feeds a pool pump, some outlets and a pool heater which is no longer used (50amp). I have built another shed 30 ft from the sub panel which I want to bring power to. I need 1 - 30amp outlet and at least 2 - 15amp breakers to...
Hello, this is my first post here. I have a little experience with most types of household wiring through a decade of DIY remodeling, and building a new house but am not an electrician.
I'm researching options for getting power to a small cabin in the woods behind a house (Oregon, USA). It...
I have an electronic device (X Box One S) that came supplied with a 5AMP Fused figure of 8 power cable. I want to buy another cable, and my local store only stocks 3AMP fused cables of the same type.
My question is, can I just buy the 3AMP fused cable, and replace the fuse with a 5AMP one, or...
Howdy folks, new member here. Homeowner, been doing my own electric for 40 years or so, from swapping out plugs to installing an entire circuit panel. Ran into a problem a while back that I still can't figure out, I'm hoping it's something that someone out here has experience with.
A couple of...
Hi. Hope I'm allowed to post here. Something terrifying just happened and I'm trying to figure out why. I have no clue about anything to do with electrical.
I was playing my electric guitar, pretty loud and couldn't hear that it was thunderstorming outside and I was electrocuted through my...
On the other side it is the power transformer. Trying to figure out why my lg 55lf6000 screen keeps blinking in 1.5 second intervals. So I’m wondering if that spot looks burnt and hoping it is the cause. It’s just I’m wondering if that spot is normal.
Can’t click ‘complete certifcate’ button on NIC online certification and cant figure out why?????
its let me complete 3 others but wont let me do the last 1
Both legs of one ring in a socket with both legs of another adding another 8 outlets in two rooms.
I'm adding a few new sockets and will be migrating the circuit to a new RCBO populated CU so was giving it a little more attention than usual, wouldn't normally do a fig8, when i found the two...
Mondays job,
"Isolation switch for the pump keeps shorting" Location: basement
That's it, all the detail you'll ever need.
Four hour round trip.
Come on smart arses diagnoses please.
My money is on a genuine high load, motor bearing gone or some such. Turn up, clamp it, prove it high =...
Done a CU change today, brief testing before hand I knew there was a problem on one circuit, believed to be the element in the immersion tank so put the very low IR readings down to this.
Fitted new CU with plumber arranged to look at the immersion, changed it and thought that would be that...
Hi...keen amateur here......don't crucify me for asking!! I understand Ohm's law and I understand the mechanics of measuring end to end on ring final and then joining incoming live to outgoing neutral etc, and I know that this configuration gives a figure of 8 (in fact can be straightened to...
I am trying to replace a switched light fitting that is in a cupboard with a new ceiling rose. When I took off the existing fitting, I can't work out which wires are which in the existing fitting and there are no markings on the existing fitting to help. It looks pretty old and the wiring on...
Trying to get an ball park idea on costs to get 2 double sockets and a light in the garage. Blackpool Area.
New consumer unit fitted in 2014 that has spare ways.
At a guess route for cable would be from consumer unit up to loft (4m) across loft to rear (10m) then to armoured? Down outside of...
woh, long title, sorry. I ask because I have never clamped a cooker circuit before. I did yesterday, hob was labeled 6ka and when all 4 rings were on full, from cold, it pulled 31a for a good 5 minutes till the thermostats started kicking in. all well within the constraints of cable, but not...
Naked ladies are lovely. especially if they are fit. However, on an electrical note...
When testing ring final circuits end to end tests confirming the ring. I have recently been informed that the results for L-L and N-N should be within 0.05 ohms. I know that they should be the same, but where...
testing a ring final today
end to end test L 0.24 N 0.24 CPC 0.37
figure of 8 L1 -CPC 2 L2 - CPC 1 0.25
L1 - N 2 L2 - N 1 no reading
IR >999
cant figure out why open circuit on figure of 8 any answers?
Hi there wonder if anyone can help.....
ive tested continuity on a new ring main circuit I installed
the end to end were -
R1:0.28
Rn:0.28
R2:0.40
seems ok
The figure of 8 results I expect from that would be
L/N = 0.14 & L/E = 0.17 roughly
Although on some of the sockets the figure of 8...
