Leakage current meter - recommendations?

[AJshep]

Trouble is last time I checked ( last year) there were a handful of companys that made type B RCDs, Doepke was one of them, they were also over £100 each. Not sure if much has changed

I hope the IET are not following this post.....lads are going to well miffed,if the 19th has them dragging an oscilloscope to every job

Now you've done it ...

Lol. I doubt they are but they do seem to be pushing untestable tech from manufacturers.

Jobs for the boy's?

@l4urence hope you are well, did you ever find an answer? I am looking for the same bit of kit but can’t find any that say they measure DC. ?

Some do measure DC but the ones I have seen are expensive like this:

CP 41 | GMC-I Prosys CP41 Clamp Meter, 40A dc, Max Current 40A ac CAT III 300V | RS

@pc1966 thanks for that, You don’t know if any of the megger range measure dc do you?

I think the DCM340 does, but it appears to be only a 400A range so your resolution is something like 0.1A and no good for leakage checks.

Great for PV or car use though!
