Upon my arrival on the approved repairs of upgrading the power protection system. Installed new power protection at the indoor furnace and redid wire terminals, installed new disconnect, power protection, redid wire terminals, new electrical fittings and sealed around the disconnect. I then tested the system finding it operating properly at this time. While performing the repair I found that the breaker on the outdoor system is oversized using a 60 amp when the unit calls for a 40amp. I brought this to the customers attention and he will have an electrician install the proper breaker.
