Megger 1552 rcd type testing

[APE37]

Hi guys, just wondering with new regs and use of different types of rcd, I noticed on my bosses megger 1700 series tester there is scope for changing between different types of rcd for example type a and type ac
On my megger 1552 I can change between ac and DC but wondering if this is sufficient for testing different types of rcd or will I need to shell out for a new tester. I have tried to contact megger on Monday but they have not got back to me as of yet, so thought I'd ask here to see what others take on it is.
Thanks for any info on the subject.

Hi Mate

Your 1552 will only test Type A and AC. The DC option is for testing DC sensitive RCD'S (not Type B). If you are testing Type B RCD'S you will need to upgrade.

The 1730 will test Type B RCD'S.

Hi TJ,
Thanks for the info. Thought that was the case. Don't do anything at the mo that needs type b so will stay with what I got for now and may look at treating myself to a new megger in the future.
Once again thanks for responding.

Type B RCDs would be used where there is solar panels or a car charger.
Though in many instances they will not be necessary, depending upon on the inverter.

Hi spinlondon,
Thanks for the info. I did realise b type was for solar panels and car charger points, but didn’t realise it was dependant on the inverter. (learning something new every day)Thanks for letting me know.

The installation instructions for inverters will tell you whether type B is required.
