Volt Stick Tip.

You have to verify earth continuity before applying these tests, and what's a ramp test got to do with tripping mcbs?

How is it extremely dangerous? Obviously they would use a plug in tester to check first before using one.

A lot of sparks use this method

Yeah, right! I don't believe a word.​

It was obviously meant in jest mate, calm down lol

How is it any different to tripping an rcd?

Because when you carry out a functional test on an RCD you are exposing the circuit to millamps at the supply end throug a resistor. Deliberately shorting a circuit to test the OCPD exposes the circuit to thousands of amps, way above it's normal capacity. Let's say the breaker happens to be faulty and doesn't trip? BBQ time!

Fair enough, forgot about that tbh, same as ir is only mA

By not verifying R2 first. Think about it, what would happen if the circuit under this 'test' you speak of had a poor or non existent earth?

I knew you were joking and only pointed this out as that statement has the potential to influence lesser trained members/readers.

n-e then no drama if bad earth

They do l-n though

I have a plug top shorted out L-E, very useful, but I have never used it on a live circuit. :S

Got a Megger DCM 330 a while back,to leave in the Patrol,has a voltfinder function which is,i suppose,a glorified v-stick. It has been extremely useful,quickly pointing me in the right direction on many occasions,quite sensitive too...NOT a substitute for other test gear,but if it gets chored,i would certainly replace it. But i also bought the "x-ray glasses" off the back of a comic when i was 10,so...

An early Pervert, ....and a Gullable Pervert at that!! lol!! :icon6::seeya:

If its a socket I know a few guys that trip the breaker using a plug top and then see which mcb has tripped

I remember one job it was an outside light in a hospital,very old building and the board was an old mem with about 50 rewireables in,anyway non of it was marked up so the old spark just shorted the feeds at the light and blew the fuse.I asked him how he was going to find it later,his reply was a classic "I'm on holiday for a week from tonight,let some other bugger look for it".
