EV Charging
EV Charger Installation in Medina, WA
The charger is usually the largest single load a house here ever adds. Whether it needs a sub-panel or two spare slots is arithmetic, and we do it before quoting. Ask on (000) 000-0000.
Have it estimated free — (000) 000-0000A charger is a continuous load, sized at 125 percent of its rating, so a 48-amp unit wants a 60-amp breaker. On larger houses the service is often adequate while the panel is simply full, which turns the job into a sub-panel rather than a service change. Garages set well back from the house add a distance question on top.
How it runs
What the job looks like
01
Calculate what is spare
We total the connected load and the real demand rather than using a rule of thumb.
02
Plan the position and the run
Where it hangs, how the cable gets there, what the distance does to conductor size.
03
Install and prove it
Circuit in, charger set to the right amperage, watched through a full-rate charge.
Detail
What we watch for
- Load management before upgrading — sharing capacity is usually cheaper and overnight charging never notices
- Conductor sized for the run — a long feed to a detached garage needs upsizing, not optimism
- Cable reach measured to the port — not to the nearest wall
- Permit filed and inspection met — EV circuits are inspected work
Questions
Asked often
Will this force a service upgrade?
Often not. A 200-amp service usually has room once the load is calculated honestly, and where it does not, a load-management device lets the charger share capacity rather than forcing a service change.
Can the charger go in a detached garage?
Yes, and it is common here. It becomes a question of the feed to that building: its size, its condition and whether it has a proper ground. We check that before quoting the charger itself.
Have it looked at before you commit
Describe the job on the phone and we will say what is involved and whether it needs a visit to price properly.
