Estimate carefully
Calculators should point to planning ranges and review needs, not final electrical decisions.
Principles
No pretend certainty
Home utility decisions touch safety, cost, permits, and local rules. The site family should be useful without pretending to replace licensed review.
Show the basis
Readers should be able to see the assumptions behind local cost, permit, utility, and incentive guidance.
Protect the reader
No pretend rankings, rating stars, or hidden lead handoffs dressed up as neutral advice.
