so lost -electrical requirments please help
I have never seen two dedicated 30 amp circuits for one heat pump, unless you are in fact installing two heat pumps. That said, if your system is a split system, the heat pump will be outside, and then there will be another indoor unit (air handler) that may be located possibly in a closet, attic, crawlspace, garage etc. Now, the 60 amp dedicated circuit is required for the back-up heat strip that is installed in your air handler. Sometimes ice will collect on the coils of the heat pump. The heat pump, when this happens, will attempt to melt the ice by kind of going into a defrost mode (crude explanation but roughly accurate). When the heat pump goes into "defrost mode" it will signal to the back up heat strips in your air handler to turn on, allowing the warming of air to continue while the heat pump is temporarily out of commission. This is why you need that second dedicated 60 amp circuit.
With respect to the cost to install the dedicated 30 amp circuit, the electrician's quote sounds a bit high; however, I don't know the circumstances and what all needs fixing, so I am really pre-judging. I hope this helps. Post some more details so that we can provide you with some more info. Good luck!
