Hi;
We had a fire and are putting are building back together. I have a new heat pump that has heat strips that draw 90 amps. A new wire has to be run from the panel to the heater. The run is about 75 feet. The electrical contractor is responsible by contract to hook up all wires to the new 200 amp panel he is installing. He wants an additional 1300 to run the one wire for the heat pump. He says the wire and conduit alone will run 1000 dollars. I am debating running this wire myself. If I run the wire, he will attach it to the panel as part of the original bid to hook up all wires to the new panel. So all I have to do is put the wire in the conduit and attach it to the wall. I would like to weigh the cost. What is the correct wire size that will be needed for 90 amps?
Thanks Pat
