7 Out of 10 Homeowners Prefer Generac Generators

AMJ Electric LLC is your local one stop shop for Generac generator installs, service, maintenance, and sales in the Southern Maryland region.

Power outage? No problem.

Power outages are becoming more frequent! A permanently installed Generac home backup generator will protect your home automatically. It runs on natural gas or liquid propane fuel and sits outside your home just like a central air conditioning unit. The generator system delivers power directly to your electrical system in the event of a power outage ensuring you have power to your entire home or just the most essential items. When utility power is lost, your Generac generator system equipped with a transfer switch will sense this, start your generator and in 30 seconds power will be restored. When power returns, your generator will go into a cool down cycle and go to standby mode for the next outage.

We also provide options for manual transfer generator systems. This type of installation will have to be paired with a portable generator. A manual transfer switch will be installed inside your home close to the electrical service panel. Selected circuits will be removed from the home's electrical panel and reinstalled in your generator transfer switch. A 30 or 50 amp inlet box can be placed outside to allow generator to be plugged in and power your selected items during a power outage. This option is a little more work to operate during a power outage, but is cost effective.
