Dedicated circuits
Dedicated Circuit Installation in Sammamish
When one appliance takes out half the house, the appliance is usually not at fault.
Heavy loads deserve their own supply
Large houses accumulate large appliances, and plenty of them end up sharing circuits that were never meant to carry them. A kitchen running a microwave, a kettle and an air fryer on one run will keep tripping, and resetting it changes nothing. A dedicated circuit runs from the panel to one piece of equipment and nothing else. It is the fix for appliances that trip under load, shop tools that dim the lights on start-up, and detached garages or pumps that were fed off the house years ago as a temporary measure.
What is included
The right size, not the biggest
Conductor and breaker matched to the equipment nameplate, which is the only number that matters.
A route planned for the building
Crawl space, attic or conduit, with underground runs out to a shop or detached garage.
Panel capacity checked first
If the new circuit pushes the service past what it can carry, you hear it before we start.
Permit, inspection and labelling
Filed where required, inspected, and the breaker marked so the next person knows what it feeds.
Why people call
The breaker goes on start-up
Motors and compressors draw far more starting than running, and a shared circuit often cannot take it.
Lights dim when something kicks in
Voltage drop under load — too much on one run, or a run too long for its size.
A new appliance has arrived
Ranges, wall ovens and air handlers are designed to sit on their own circuit.
There is a shop or detached garage
Fed off a house circuit, these are a common source of trouble on bigger lots.
How the work runs
Read the nameplate
The equipment states what it needs; we start there.
Check the panel
Spare capacity and a free slot, or the options if there is neither.
Plan and run
Shortest practical route, properly supported and protected.
Test and inspect
Under load, then signed off and labelled.
Questions about this work
How do I know I need one?
If one specific appliance causes the trip, almost certainly. If it trips at random with nothing unusual running, that is more likely a fault — a different job, worth diagnosing first.
Can you run power to a detached garage?
Yes. That is a feeder rather than a single circuit, usually underground, with a disconnect at the far end. Quoted properly rather than run on a cord.
Will my panel take another circuit?
Often yes, and where it will not there are usually answers short of a service upgrade.
