I’m planning on purchasing the North America Bundle, but have a few pre-purchase questions, primarily regarding the rating and number of CTs that I’ll need:
- Do the power supply and reference transformer need to be on different circuit, or can they use two plugs on same outlet (or an adapter in a single plug)?
- My municipal supply enters the main panel via a breaker labeled 200A. The breaker appears to be an Eaton BW 200 10k model, and has two very heavy duty black wires attached at the top. Will I need one or two 200A CTs for the main power supply?
- The circuit breaker for our solar power system has two 25A breakers, and the solar system is labeled as operating at 240V / 18A. Do I need one or two CTs for this system?
- The circuit breakers for the dryer and range are combined in a strange way, consisting of four breakers for 30A, 50A, 50A, 30A with the 30A ganged together (outer) and the 50A ganged together (inner). Presumably the 50A is for the range and the 30A is for the dryer. Will a single 50A CT suffice if I just want to monitor the dryer circuit (we don’t have an electric range)?
- The other circuits I’d like to monitor individually all have 20A breakers, but I see that the minimum rating available is 50A, and there are two types of 50A CT available, one labeled “AccuCT 50A x 10mm split-core” and the other “Current Transformer 50A x 10mm split-core”. What’s the difference between these, and which is recommended?
Any advice on these questions would be much appreciated.
