Issue:
Compressor RLA% does not match what amp probe is showing.
Resolution:
RTAA, RTWA, RTUA:
Compressor RLA is annunciated on the display in a percentage (%) of the run load amps. Check the RLA of the compressor and note. Next, use an amp probe and measure what the current is and divide this by the compressor nameplate RLA. Multiply by 100 to get RLA%. If what the panel annunciates does not measure what is measured, check for the correct CT's and make sure the current overload settings are set correctly.
