TEST LEADS FOR RCBO TESTING

[Dartlec]

Fluke Twistguards are probably what you want. Got some for my Megger and they have come in so handy I couldn't go back to any other type now.

Fluke make long reach/narrow probe tips

Fluke 8845A 8846A Tip Adapter Set - Extended Fine Point Tip Adapter for the Fluke 884X Series Digital Bench Meters

Is this the sort of thing you are after?

Thanks, Yes possibly , if they are meant for the multimeters and not just the hand held voltage meters.I'll have to ring them up

Make up some short (100mm) leads with a 4mm socket at one end and a bootlace ferrule at the other.

Don't forget to use safety 4mm plugs!

For example:

RS PRO Red Male Banana Plug, 4 mm Connector, Solder Termination, 10A, 1000V, Tin Plating | RS

nice one, i'll check and see how long they are

The issue stems from the likes of GS38 safety requirements for not touching the probe tip while working and having less chance of accidentally shorting (and potential for a serious arc-flash incident if on the tails, etc).

The Fluke Twistguards look interesting, must try and get some for myself!

I don't know much about the 1662, but does it not come with the mains lead to plug into a socket on the circuit to be tested?

They go from 4mm to 19mm according to Fluke - Not sure what the depth of the RCBOs involved are but that should be enough I would have thought.

They don't actually advertise them as GS38 Compliant, perhaps because they aren't spring loaded so wouldn't comply when retracted. However, that's no different to the older Megger ones with removeable covers. These are far more convenient because you don't immediately lose the covers...

It's surprising how often my old GS38 tips were defeated by a recessed choc block terminal..

They do them as whole test leads too, but I prefer to have the leads separate for a break out box.

I'm old fashioned I just shove a 3.5mm accessory hole down the recess, no I'm not joking.

Extract from the manual:

RCD Tripping Time Measurements In this test, a calibrated fault current is induced into the circuit to cause the RCD to trip. The meter measures and shows the time required for the RCD to trip. You can do this test with test leads or the mains cord. The test is done with a live circuit.
