Generator hookup in Clark County

The generator is the easy part. We do the electrical side: an inlet box on the outside wall, a transfer switch or interlock so the house can never backfeed the utility line, the standby circuits picked and moved, permit and inspection.

What it costs

Ranges for permitted hookup work in Clark County, for the electrical side only. The estimate is free and we give it in writing.

Interlock kit and inlet box for a portable generator
$900–1,600

$1,400–2,400
Automatic transfer switch for a standby set
$2,200–4,000

Distance from the panel to where the generator stands is the main swing. A pad and a long run cost more than a cord on the same wall.

Signs it's time

01You already own a generator and run cords through a windowAn inlet and an interlock end that.
02A well pumpNo power means no water. On rural properties this circuit usually decides the job.
03Somebody at home depends on equipmentOxygen concentrator, CPAP, a medical fridge. Planned onto the standby side in advance.
04Freezer full of food and a long drivewayOnce a tree comes down, outages here run days, not hours.
05Backfeeding through a dryer outletIt energises the line outside your house. Illegal, and it kills line crews.

How the job runs

01We look at the panel and where the generator will standPanel make and model decides whether an interlock exists for it. Free, usually within a couple of days.
02We pick the standby circuits with youWell pump, furnace, fridge, some lights. What a 7500W portable actually carries at once.
03Written estimateSwitch or interlock, inlet, wire, labour and permit shown separately.
04Install dayInterlock and inlet, most of a day. Transfer switch with circuits moved, one to two.
05We test it under load and label itWe start it, transfer, and watch it carry. The procedure goes on the panel door.
