I started filling my shopping cart to purchase and noticed that the smallest CT’s they sell are 50 amps!
Those would work great for my off-grid and solar feed breakers, but most of the loads in my home are on 15 amp breakers.
The problem is that, upon looking up the specs on these things, they lose accuracy below 10% of their rated current. So a 50 amp CT would be less accurate below 5 amps. That’s 500+ watts! Most of the loads in my home are in the 20 to 100 watt range, which is 5x to 25x below the accuracy threshold of the 50 amp CT’s Iotawatt sells.
Why don’t they sell the 20 amp units?
Is there a recommended alternative? I can use either split core or solid, makes no difference to me to pull a wire out of a breaker to slip a solid core CT on it.
