Same as above and what is the amp load vs. the amp rating of the low side.

Air handler normally doesn't have a transformer. It is 120 or 240 with a start or start/run capacitor. You question is a bit confusing. Heading says "low voltage" but body says "high voltage". Typically there is a low voltage transformer for the control panel and thermostat with a fan relay that closes and allows the 120 or 240 voltage through. Please clarify exactly what is happening.
