How to sell charger and panel work honestly

The panel is where most EV charger jobs in older homes get complicated. A Level 2 charger is a large continuous load, and the National Electrical Code treats it that way, sizing the circuit at 125% of the charger's rating. That means a 40-amp charger needs a 50-amp circuit and a 48-amp charger needs a 60-amp circuit. On a home with 100-amp service and an electric range or a large AC unit, the numbers can get tight quickly.

Start with a load calculation, not a sales pitch. The code provides methods for calculating existing load, and in some cases allows you to use a year of actual demand data from the utility. Doing the math in writing, and showing it to the owner, immediately sets you apart. Many owners have been told flatly that they need a new panel, without seeing why, and that leaves them suspicious.

Explain the middle options. Automatic load management, sometimes called an energy management system, can reduce or pause charging when the rest of the house is drawing heavily. The NEC permits such systems to be used in sizing the load, subject to the applicable code edition and your local authority. A lower-amperage charger may also be plenty for an owner who drives moderately and charges overnight, since charging all night at even 24 amps adds a lot of range.

Know when to recommend an upgrade. Some panels really should be replaced. Federal Pacific and Zinsco panels have well-known safety concerns, and damaged or double-tapped panels shouldn't get more load. A home that also plans a heat pump, an induction range, or solar may benefit from going to 200-amp service now. Present that as a choice with costs and reasons, not as a requirement unless it really is.

Set expectations on time. Service upgrades usually involve a permit, an inspection, and coordination with the utility, which may have its own schedule. Tell owners about the time involved up front. Quote the charger and panel parts separately, so they can see what each costs, and consider offering a phased plan where it's safe. A simple chart of options can do much of the selling for you.

Target with care. Year built is a good proxy for service size, but homes get upgraded, and a 1960s home might already have 200 amps. Say 'may' in your copy, and let the panel photo confirm it. Mention that electrical work is performed by licensed electricians where required, and check your state's licensing rules. Separately, if the federal 30C credit comes up, tell owners that it ended for equipment placed in service after June 30, 2026.
