TEST LEADS FOR RCBO TESTING

[NICKYNUNN]

Hi, what do you guys use to test rcbo trip times at the rcbo in DB? My Fluke test lead can not reach far enough for contact, I can't see any long reach probes for the Fluke 1662.
Any advice greatly appreciated

Some probes , you can pull the covers off the tips

Thanks,you can on mine but they are still not long enough :/

Make up some short (100mm) leads with a 4mm socket at one end and a bootlace ferrule at the other.
Put the bootlace end under the pinching screws and plug your test set into the other end. I always carry a couple of these leads and find them useful in many locations.

Thanks,sounds like a good work around. You'd think there would be long reach leads for this, looks like there is a gap in the market

I was going to suggest exactly the same; when test lead plugs split I keep them and use the plug other end to make up this sort of thing.

The other last resort solution, based on what I secretly used to do when I had a separate RCD tester that was only intended for socket circuits and had a moulded 3 pin plug on it and needed to test other circuits...

Stick an unswitched double socket in a surface pattress. Plug in the 3 pin plug lead for the fluke.
In the other half of the socket use a Megger/Kewtech etc 3-pin plug to 4mm lead, and any 4mm probes of your choosing. Rather a horrible clunky hack but works.

Thanks, I might get myself on dragons den with some long probes, see if any of them wanna back it

Long reach probes are a bad idea for sparks as you might be tempted to use them in inappropriate locations. Tim's idea works and is safe but as he says a bit clunky. The little 4mm to bootlace leads are easy to stick in a corner of your tool bag so they are always handy.
