Two test leads, one port

[Haworth]

Hoping someone might be able to help. I’ve seen an ‘adaptor’ that allows 2 test leads to run from one port of an MFT (doing IR test). But, can’t find anywhere to buy it. Anyone know where I could get one from?

What's the point though, as opposed to croc-ing L+N in a single clip?

I’m with you Tony.....just trying to build a picture of what @Haworth is talking about

Non really, just wanted to know if you could buy these things.

Kewtech do a pack of 4 shorting links with a Croc clip at both ends, this is what I use for this sort of thing.

Quite often in a DB the live and neutral terminals can be quite far from each other and its less messy to add a test link between the two than drag one conductor out of a big bunch of cables.

Sure be has them on this vid

L-to-N is that a louder bang test ?
(instinctive muscle memory -scares me at times)

Do you mean like this?

I'm a little confused by this thread to.
For an IR test where you are joining L and N, you are joining the L and N of the outgoing conductors not the test leads.

I can't understand why everyone is so confused. Sometimes you want to do some test or another from A + B to C. For an IR test that might be L+N to E, or L1 + L2 + L3 to E or whatever, which if you have stackable test leads, you can achieve by putting one clip on each conductor and stacking / piggybacking the leads if they are stackable. It reduces the number of things that might come apart or ping off during the test, vs jumpering with separate croc clip leads. In electronics lab work, joining, branching and daisy-chaining test leads is normal so most bench test leads have a piggyback socket.

I keep a set of touchproof stackable leads and probes in the testing kit to make up whatever configuration is required. They are only for dead tests though as they are not CAT III rated.

Ah, Lucien's post has helped. The wording of the question made me think the OP was trying to do some sort of different test by using both ports of the MFT.

That’s cleared that up then.....thanks @Lucien Nunes

Oh yeah, that's a good idea

It's called a piggyback adapter. Close thread.

I was always under the impression that if you individually test L to E, and N to E, without joining them together, you basically do the same test, just without the hassle of having to use piggyback leads or disconnect stuff?
