Type B rcd availability

Baldyhugh

Hi

would anyone know of a supplier where I could get my hands on a 100A 100ma type B double pole rcd? I need one to supply three variable speed inverters. I’ve done the usual google searches but can only find 30ma ones and only rated up to 63A. 
 

Thanks in advance

    This is on a farm and as such rcd protection is required on all circuits. the db that the inverters are going to be supplied from has other existing circuits connected which also require rcd protection. The sub main requires rcd protection as its a farm installation. In regards to ‘does it really need a type b rcd’, I can confirm that it does. I installed an identical inverter a while back and it tripped both an ‘a’ and an ‘ac’ rcd. Fortunately the mcb provided adequate fault protection in this instance so was able to remove the existing rcd
