Benefits Of A Home Generator

A home generator provides backup electricity when utility power goes out. Depending on its size and configuration, benefits can include:

  • Automatic backup power. Standby generators can restore power automatically after detecting an outage.

  • Essential systems stay powered. Keep selected HVAC equipment, refrigeration, lighting, sump pumps, and other circuits running.

  • Fewer outage disruptions. Maintain access to important electrical systems during longer outages.

  • No portable generator setup. A permanently installed system eliminates the need to set up temporary backup power during an outage.

Steps To Installing A Home Generator

Installing a standby generator requires planning around the home’s electrical loads, generator capacity, equipment location, and electrical connections. Wenbrooke handles the process through several key steps.

Determine Your Backup Power Needs

We identify which circuits and systems you want available during an outage. This helps determine the generator capacity your home needs.

Select The Generator And Location

We select the generator based on the planned electrical load and installation requirements. We also determine an appropriate outdoor location for the equipment.

Prepare The Electrical System

Our electricians evaluate the panel and existing electrical setup before installation. If related work is needed, Wenbrooke’s electrical services can address it as part of the project.

Install The Generator And Transfer Equipment

We install and connect the generator and transfer equipment to the home’s electrical system. The transfer equipment allows the designated circuits to receive generator power when utility service is interrupted.

Test The Backup Power System

After installation, the generator and transfer operation are tested to confirm the system responds and supplies the intended electrical loads properly.

Signs Your Generator Needs Repair

A generator should be ready to supply power when an outage occurs, so changes in performance deserve attention before the system is needed. Schedule generator repair if the unit struggles to start, shuts down unexpectedly, produces unusual noises or odors, shows warning lights or fault codes, leaks fluid, or fails to transfer power correctly during testing. Wenbrooke can diagnose the generator and its electrical connections to determine what is preventing reliable operation.

This was my first time using Wenbrooke services as we just moved into their service area. We chose them because of the great reviews. They didn't disappoint, Trevor reviewed our electric panel & receptacles & made us aware of things that needed our attention but was not trying to "sell" us services. Jorge reviewed our furnace & recommended a safety concern that we decided wasa priority & agreed to have it done. The scheduling was prompt & easy. We would highly recommend these technicians & wenbrooke.

Chris was excellent. Explained everything that was needed and did a temporary fix today to stop the leak but more extensive work is needed in the future. My husband has dementia and Chris was very patient to repeat things so my husband could understand what was going on. We will definitely want Chris to do the additional work in the future.
He is very professional and eager to be sure we understand the problem and the options we have to fix it. Highly recommend him to ur future clients.
