200 amp service vs 400 amp service do you really need a service upgrade, or are you just being told that because your electrical panel looks full? In this video Dustin walks through real world scenarios like EV chargers, pools, hot tubs and gas to electric conversions, and explains when a service upgrade is truly required and when it is not. ⚡
He breaks down what goes into a 400 amp service the trenching, bigger conduit, larger conductors, CT metering, transformer changes and inspection headaches that make these jobs jump into the ten to thirty thousand dollar range in many areas. You will see why simply having a packed panel or a big stack of breakers is not the same as having a true 400 amp load on the service. Instead, Dustin walks through demand and diversity, and why Article 220 load calculations and service entrance conductors are what really set the limit.
