Heat Strip Staging
Quick questions: I have a 3 ton Carrier HP and the tech has installed 15 kw of heat strips. We had a 60 amp circuit hookup and he has said that we need an 80 amp and that 15kW is neccessary for this unit to perform properly. the question are:
1) I have read that 10kw is plenty for the size unit and home (1800sq ft ranch), Is this true?
2) Tech said that the strips cannot be staged from 5 to 10 to 15 in sequence, but only 10kw first and then 15 if needed. Is this correct?
3) What needs to be explained here so I can understand this better?
