The 50 amp CTs for monitoring the individual loads are mostly a “one size fits none” solution. Except for the big 220 V loads (Dryer, HVAC, Stove, and subpanel feed to the garage, all my breakers are 20 amp, and the biggies are either 50 or 70 amp. So the 50s are mostly wasted on breakers that are going to trip at half their capacity, and the one I have on the 70 will saturate if it ever goes close to capacity (although the new HVAC unit on the 70 amp breaker I got to replace the 15 year old one that died last spring doesn’t seem to go over 40 amps even at full draw). But looking at adding another Vue 2 to monitor more circuits than the current 16 (the panel has 42 slots , but 10 of them are circuits so rarely used that I can ignore them), I’m not sure I can FIT 32 50 amp CTs in the panel; if I could get (even buying them separately) a dozen or so physically smaller 20 amp CTs to match the breakers, it would make it a lot easier to cram them all in there.
