01
We calculate before we quote.
Every proposal starts with a load calculation, not a guess. That's why our estimates don't change halfway through the job.
Capabilities
Four disciplines. One standard.
Most Seattle homes were wired for a toaster and two lamps. We bring them up to what a modern house actually draws.
How We Work
Four steps. Passed the first time.
I
Load Calculation
Before anything is quoted we calculate your actual service load per NEC 220. You find out what your panel can carry before you spend a dollar.
II
Permit & Plan
We pull the permit, coordinate with Seattle City Light or your utility, and schedule inspection. You never chase a jurisdiction.
III
Installation
Master electrician on every job. Circuits mapped, panel directory typed and laminated, work photographed before the walls close.
IV
Inspection
We meet the inspector on site. If something needs correcting, it's corrected the same day and you're not billed for it.
Load Planner
Will your panel carry it?
2,200 sq ft
Current panel size
Existing loads
Planned additions
123A of 100A
123%
This exceeds your service. You'll need a panel or service upgrade first.
- A 100A service is the constraint here. A 200A upgrade resolves it in one visit.
- Swapping the electric water heater for a heat pump model frees roughly 14A.
Preliminary estimate. A licensed electrician must perform the full NEC 220 calculation before permitting.
Why Northwire
The standard, quietly held.
02
A master electrician on every job.
Not a helper with a phone number to call. The person doing the work is the person who can sign for it.
03
First-pass inspection or we eat it.
We meet the inspector ourselves. Any correction is handled the same day at our cost.
