How many quotes should I get in Sunnyvale?

Get at least three written quotes from licensed, insured California contractors. Comparing line items — not just the bottom line — is the fastest way to spot an inflated bid in the Bay Area market.

How much does a 200 amp panel upgrade cost?

$2,000 to $4,500 typically, or $2,800 to $6,000 if the meter base and service entrance also need replacing.

How long does a panel upgrade take?

One day for the electrical work, with power out four to eight hours. Utility scheduling and inspection may spread it over a few days.

Do I need 200 amps for an EV charger?

Usually. A Level 2 charger draws 40 to 60 amps; most 100 amp services cannot support it without load management.

Is a permit required?

Always. The utility will not reconnect without an inspection sign-off, and unpermitted work surfaces during a home sale.

What are Federal Pacific and Zinsco panels?

Obsolete panels with breakers that fail to trip. Insurers often refuse coverage and replacement is strongly recommended regardless of capacity.

Can I just add a subpanel instead?

A subpanel adds circuit space, not capacity. If your total service is maxed out, you still need the main upgrade.
