Home Standby Generators

A home standby generator is permanently installed on a pad outside the house, wired to a transfer switch, and fueled by natural gas or propane. It starts automatically within seconds of an outage whether or not anyone is home — no cords, no fuel cans, no manual switching.

Urban Supply carries the Champion Power Equipment standby line, including the 22kW FLEX and 22kW aXis platforms with 100A, 150A, and 200A whole-house service-entrance transfer switches in NEMA 3R outdoor enclosures.

Whole-house vs. essential circuits

A 22kW unit with a 200A service-entrance switch backs the entire panel — nothing gets prioritized, nothing gets shed, the house simply runs. Smaller transfer switches back a subpanel of essential circuits: furnace, well pump, refrigeration, a few outlets. Essential-circuit installs cost less and are the right answer for a smaller service, but they require deciding in advance what you are willing to live without.

What the install actually involves

  • Licensed electrician for the transfer switch and panel tie-in. This is not DIY work and most jurisdictions will not permit it as such.
  • Licensed plumber or gas fitter to run and size the natural gas or propane line. Undersized gas line is the single most common cause of a standby unit that starts and then stalls under load.
  • Permit and inspection in most municipalities, plus a utility notification for natural gas.
  • Pad and clearance — a level composite or concrete pad with manufacturer-specified clearance from windows, doors, and vents.

Budget for installation separately from the unit; it is frequently a meaningful fraction of the total project. Call us before you buy and we will help you match generator size to your service panel and gas supply.

Free US shipping on orders over $299 (certain exclusions apply). Authorized dealer pricing with full manufacturer warranty. Call 917-540-6070 (Mon–Fri 9am–6pm EST) for fitment or spec help before you order.
