Cummins RS20A installation with your household in mind

Start with a backup plan you can picture

Tell us what your household needs during an outage, from refrigeration and lighting to heating controls, communication and pumps. We review the electrical loads behind those needs and discuss which larger appliances can wait. That helps us build a plan you can actually use, rather than an undefined promise about the whole house.

We account for starting demand as well as running loads. If managing selected appliances helps the design, we explain what you will notice and which priorities remain available. You should understand the daily experience before deciding on equipment.

Snohomish County PUD explains that fallen trees and brush can obstruct access to damaged lines before repair work begins. We do not turn that into a prediction for your street. We use it as a reason to discuss a workable household routine while the utility restores service, including food storage, useful lighting and the loads you can comfortably defer.

We make the Cummins package easy to compare

Cummins distinguishes the RS20A generator from the RS20AC packaged configuration with transfer equipment. We identify the full ordering details and the actual switch in your scope, so an equipment listing or photograph does not leave an important part of the project unclear.

For a replacement, we inspect the existing transfer arrangement before recommending reuse. Condition, controls and the supported combination matter. We also confirm the applicable fuel-specific rating and model documentation so the design reflects the equipment and fuel your home will actually use.

Choose capacity for a reason

The RS20A and RS17A comparison becomes useful when it answers a household question. Will the larger plan support an additional priority, accommodate a demanding starting load or reduce an operating compromise you would rather avoid? We show you those differences against the same appliance list.

We also look ahead. If you are planning a heat pump, kitchen renovation or another significant electrical change, tell us now. Future loads do not automatically belong on backup, but knowing about them helps us discuss the system you want to live with.

Fit the installation to the property

We review the proposed outdoor location alongside electrical routing, fuel access, building openings and service space. Drainage and equipment access matter too. The closest spot to your electrical panel is not always the best place for the full installation, and we explain the practical alternatives.

For your King or Snohomish County property, we use the address to establish the applicable jurisdiction and utility coordination. We identify any service changes and fuel-provider work early so those pieces can be considered before the location and installation scope are finalized.

Know what our quote includes

Generator supply, transfer equipment, feeder routes, trenching, site preparation and load controls can all affect the project cost. We make our electrical scope clear and identify separate responsibilities for fuel work, engine startup and ongoing service. A useful quote tells you what is included and what still needs confirmation.

When you contact Live Wire, photos of closed electrical equipment and possible outdoor locations help us prepare. Include your fuel type, major appliances and any existing generator information. We can then focus the visit on the decisions that will make backup power useful at your home.
