Suitable CT clamps for M30

Posted by: sumnerboy - 11-27-2024, 08:33 PM - Forum: KC868-M16 / M1 / MB / M30 - Replies (23)

	Hi, I am very interested in getting an M30 for monitoring the various circuits in my home. Some circuits only draw a 1-2A, some 8-10A, some 20-24A. Can you please provide a list of suitable CT clamps that will work with the M30 for a various range of currents? Ideally model numbers and specifications so we can source them directly if required. Many thanks, Ben
