First-edition questions
53 specific questions are published in this edition. 84 further phrasings are in the inventory for later expansion once we can see which pages are actually found and cited.
Each published page is written to answer that phrasing directly, with a worked example or a dated table, not as a retitled copy of the overview. The sources page lists the methods behind the calculators.
Panel capacity and EV charging
Can a 100-amp panel support a Level 2 EV charger?Can a 150-amp panel support a Level 2 EV charger?Can a 200-amp panel support an EV charger and an electric dryer?Can I add an EV charger and a heat pump to a 100-amp panel?Can I add an EV charger and a heat pump to a 200-amp panel?Does my panel support an EV charger and a dryer at the same time?40 amp vs 50 amp EV charger: which circuit do I actually need?Do I need a 60-amp breaker for a car charger?Why is EV charging a continuous load, and why do electricians use 125%?What is a residential load calculation for an EV charger?Can I use 12 months of utility peak demand to see if I can add an EV charger?Load management vs a panel upgrade for an EV charger: which should I consider?Open breaker spaces vs service capacity: why can a panel look empty and still be full?Can a 100-amp, mostly gas-appliance house take a 32-amp Level 2 charger?Can a 100-amp panel with an electric range take a Level 2 charger?Will a 48-amp Tesla Wall Connector fit on a 200-amp panel?Should a Level 2 EV charger be hardwired or plugged into a NEMA 14-50 outlet?Can I plug an EV charger into my dryer outlet?My main breaker is 100 amp but the panel label says 200 amp. What does that mean?32-amp vs 48-amp EV charging: how much faster is the bigger circuit?
Service upgrades and cost
How much does a 200-amp panel upgrade cost?What is actually included in a 100-amp to 200-amp service upgrade?Do I need to upgrade the meter base when I upgrade the panel?Can I add an EV charger or a generator to a fuse box?Is 200 amps enough if I have an EV charger and a heat pump?How do I read the amp rating on my electrical panel?
Backup power and generators

Heat pumps and operating cost
Heat pump vs gas furnace: which costs less to run?Is a heat pump cheaper to run than a gas furnace in California?Is a heat pump cheaper to run than a gas furnace in Washington or Idaho?Is a heat pump cheaper to run than a gas furnace in Massachusetts or New York?What is HSPF2, and why can’t I compare it directly with AFUE?What does a COP of 1.75 at 5°F mean on a cold-climate heat pump?Dual fuel: when would a heat pump switch over to a gas furnace?Ductless mini split vs a window air conditioner: what’s the real difference?What size mini split do I need?Do heat-pump backup heat strips mean I need a panel upgrade?Will installing a heat pump require a panel upgrade?How do I compare heat-pump running cost using last year’s gas bill?
A machine-readable inventory, including backlog phrasings and source types, is kept with the project (questions_inventory.json) and summarized in QUESTIONS.md.
