I am installing a RHEEM UHLA-HM4821JA Air Handler that will contain a 15kW RXBH-24A15J Heating Element. Per the manual I can wire the heat strip one of two ways, either I can buy a 2 pole jumper RXBJ-A21 and run a single power run or run two separate power runs one to each of the power strips two breakers (60A and 30A).

I have run 2-2-2-4 (100 A) Aluminum from the home's outside service to a 125A 8/16 load center place about 2 feet from the air handler. The load center will accept up to 4 double pole breakers. I plan to run copper from the load center to the air handler.

Am I better off running separate runs to each of the heat strips elements or buying a the RXBJ-A21 jumper and running one larger single run. I believe I will need 60A and 30A

Two posts and no answer.

Follow the manufactures instructions that came with the unit.

Run two is always preferred in my book.

I hope this is not in a mobile home. The furnace needs to be listed and labeled for that use.

Thanks HVAC.

I will take your advice and use two runs. I feel more comfortable doing that too. Rest assured, this is not a mobile home. I plan on helping my son soon to eventually go through all the wiring in the house, ripping out all the code violations the previous owner put in.

Are you planning on installing the A/C unit yourself as well?

Only the electrical. I've done a lot of AC work in the past and was certified but its something I really dislike doing. I figure my daughter has all winter to save up to have someone come out and braze the lines, charge the system and check it out.

Right now she needs heat.
