RCD's On lighting etc

[danny124]

Hi guys wondering if you can help.

I did my 17th update as i took a break from the trade for a few years. I finally go back to my firm tomorrow and its all changed.

Trying to get my head around the RCD stuff.

RCD's on everything now right including lighting thats not capped etc ect

Do we split the lighting on one RCD and sockets on another?
Dont light bulbs lamps when they blow trip the RCD's and then clients are going to get annoyed that either all there lights are out or there whole floor is powerless.

And testing, how do we test RCD's on lighting we arent allowed to do live testing on exposed parts due the the electricity at work regs.

Could someone help me.

Thanks for your time guys

Kind regards

If its that much of a problem, test at a switch. No probs pilling from the wall live, if you have fitted correctly as there should be nothing live to touch with your bare fingers......
Plus the switch should pretty much be one of the furthest outlets in the circuit, its also in easy reach and simple to test. Ad as I said before, get the lamp adapters from Kewtech, makes it all so simple (and safe).....

The 32A for the NH are fine and you can use the screw at the front. The 6A ones have the N and L the other way round though so the screw for the L is about an inch inside the housing and a probe won't get in. I was worried about leaving it live while walking back to reset the RCBO as I have my NIC inspection on Friday and sod's law says he'll want that circuit for the RCD test I have a light adaptor for the L & N but would have to have the rose cover off to get at the earth and leave the tester on the top of a set of steps while I went to the board to reset the RCD. Not sure what the inspector would think of this

Which meter are you using ?
Do you still have the plastic tip covers on the ends of the probes which cover all but the very end. ?
My megger had them but they are removed as a norm, unless / until I'm being assessed..!!

The Megger 1553 comes with a long insulated probe that screws onto the switched test probe.

I've got a fluke 1652, and with the little nipple things taken off it still doesn't reach in! Yet another reason why I should have got a Megger. I might stick mine on ebay and get one actually, wonder how much it'd cost for an upgrade

Ah... I see why you have an issue now. !
The standard megger probes (without guards) fit into the wylex rcbo's no problem..
Can you not just get some different probes for yours ?
