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...
Morning
i have calculated my max demand as 69.6a (sum of mcb's x 0.4)
and on my eic i have n/v the main head fuse- but on the sticker it says 60/80a (i know it could actually be 60 or 80 or 100 inside)
this is the job i am using for my niceic initial assessment

Hi
Running a quick test on a lighting circuit today, was doing R1 + R2 on downstair lights. Everything seemed OK, but upon trying to prove polarity by using switches obviously upon switching off the circuit goes open but when tried switching on again and testing again I got a wildly...
why do we have to do the calcs to 230v when the supply never is 230v
measured voltage at source is 248 volts at the site i am on at the moment ,
can somebody shed some logic on the idea before i start engineering an 18 volt drop into my cable sizes
( a joke of course but why not ? ) :ihih:
Hi, Doing 2395 revision and doing a small temp builders supply therefore TT . Installed 2 x 13a sockets protected by 16amp breaker and 30ma RCD.

I've just been flicking through the regs to do some cable calcs for a job and noticed that a 4mm 2 core cable installed using method B (under floors etc) has a capacity of 30A. However it is ok to connect to a 32A MCB for a radial socket circuit. Don't know if its just me missing something...
Im at the fuse board and there is a fault with one of the lighting circuits. Cut a long story short when the Live is in the breaker the neutral becomes live aswell.
So I presume its a short circuit, I isolate the power and test continuity between Live a Neutral (My tester is calibrated and I...
Hi this weekend my wife and i made a spontaneous purchase and bought a new LED Samsung TV. The existing LG TV that is wall mounted in my living room has the wires channelled through the wall. The LG uses a power cable called a kettle power lead. The new Samsung has a figure of 8 power lead. So...
