Notes

  • Where the number comes from. The national price for a 400-amp service upgrade is $6,000 installed — service panel upgrade pricing published for 2026. Labor is about 68% of that. Electricians near Salem, OR average $94,980 a year against a U.S. mean of $71,490 — a factor of 1.329 — so the labor half is scaled by that and the material half is not. Source: BLS OEWS May 2025 for the Salem, OR metro area, SOC 47-2111.
  • Why the city matters, not just the state. Trade pay moves inside a state as much as it does between states. Crews do not commute across a state to bid a job, and materials ship at national prices either way — so a metro wage is the honest input here and a state average quietly rounds four different cities into one number.
  • What is in the price: the panel, breakers, a new meter base, grounding electrodes, the service mast, permit inspection time, and labor.
  • What is not: the utility drop, trenching for an underground service, any rewiring inside the house, and repairs to walls the mast passes through. These are the lines that turn a $7,341 quote into a $9,176 invoice, so ask about each one before signing.
  • Use this as a bid check, not a quote. It prices an average job in average condition. Difficult access, the state of what is being replaced, the season, and a crew booked out three months all move the real number, and none of them are in a national average for the job.

What the quote should include

The lines that turn a quote into an invoice

Ask about each of them before you sign. On a job this size they are the difference between $7,341 and something a quarter higher.

Use it as a bid check, not a quote

This prices an average job in average condition. Access, the state of what is being replaced, the season, and a crew booked out three months all move the real number, and none of them are in a national average.

If a bid lands outside $4,894 – $11,011, that is not automatically wrong — but it is the question worth asking out loud.
