A Portland service upgrade replaces the meter base, service conductors and usually the mast, not just the breaker panel, and the size comes out of a load calculation rather than a rule of thumb. Covers the Oregon amendment that lets an existing panel stay where it is, the PGE rule that ends grandfathering on your meter location, and the three requirements Oregon does not impose.
Hot tub wiring in the Portland metro runs roughly $700 to $3,400 installed in 2026 for a standard 240V, 50-amp hardwired spa. The number lands at the low end when your panel has spare capacity and the tub sits within about 40 feet of it, and at the high end when the...
A faint hum you can only hear with your ear near the panel is usually normal. Breakers and transformers vibrate slightly at 60 hertz when current flows through them, and that sound is not a fault. Loud buzzing, crackling, popping or a sizzling sound is a different...
An arc-fault breaker that keeps tripping is almost always reporting something real, and the pattern of the trip tells you what. A breaker that trips the instant you reset it points somewhere very different from one that only trips when the vacuum runs. Before anyone...
Portland loses power more often, and for longer, than most cities its size, and the reasons are specific to this place: mature trees standing over old overhead lines, ice rather than snow, and hills that slow crews down. In January 2024 that combination produced the...

A panel upgrade in Clark County runs on a different set of rules than the same job across the river, and the first question is not cost, it is which agency issues your permit. If your address is inside Vancouver city limits, the City of Vancouver permits and inspects...
On September 1, 2026, the Oregon exemption that has kept outdoor heat pumps and air conditioners off ground-fault protection expires. From that date, outdoor HVAC outlets at homes fall under the same GFCI requirement as the rest of your outdoor electrical, and...
If an outlet is actively smoking, stop reading and go shut off that circuit at the breaker panel. A smoking outlet is not a warning that something might go wrong later. It means a fire has already started inside the wall cavity, and the drywall and the metal box are...
