unless some one who installed the lighting circuit originaly confused the nuetral and phase conductors it'lle be safe.
The nuetral takes the current away from the circuit, so to power a light the circuit would go consumer unit> phase> ceiling rose> nuetral> consumer unit and phase passes...

Igot some I got from the internet the other day on testing can't remember the site - google searched for "GS38 voltage indicator" and loads of stuff came up. e-mail me at [email protected]. and i'll send them as attachment
tHANKS FOR REPLYING I MEANT THE RCD KEEPS TRIPPING OUT THE CIRCUIT
My workshop is full of computers I build and sell them for extra income. anyways thats what I'm using the sockets for.
In designing the ring circuit. I counted up the maximum devices that I would be using. And took that...
i'VE JUST INSTALLED A NEW RING CIRCUIT INTO MY HOME. pROBLEM IS MY RCD KEEPS TRIPPING OUT WHEN I HAVE THEM ALL ON AT THE SAME TIME. THE CIRCUITS IN MY WORKSHOP. SHOULD I JUST REPLACE THE 32A MCD TO A 45A INSTEAD. OR SHOULD I REDO ALL MY TEST AGAIN?
I would need:
1x 50mm Pattras single
1x Single control unit No 13 a socket recquired
1x 25 mm Pattras
1x Cooker Outlet Plate (vertically below CCU)
1x 32A MCB
Grommets, Clips, etc
Now, I've already done my cable calc's chosen my cable and the instalation method. Now here comes...
I know that you have to test the continuuity of CPC's, and the polarity
its just that I can 't remeber what else. By the way I'm a trainee sparky
and this is for an assignment. The lighting circuit incidentally is a radial.
I would realy appreciatte any help. thanks.
p.s. My books...
