Discuss Fitting a 100ma RCD on Solar PV to solve nuisance tripping. in the Electrical Wiring, Theories and Regulations area at ElectriciansForums.net
Seems so from customer reports. He's been resetting the RCD and the system is working fine after that. Of course dawn is around 5.15 at the moment so he's missing out on a lot of FIT.He probably means a B type RCD.
