Backup Power When the Grid Goes Down
Generator Installation and Service in Shelby Township for homes and businesses facing frequent power outages
MJM Electric Inc installs and services standby generators across Shelby Township, providing automatic backup power when utility service fails. When the electrical grid loses power during severe weather or system failures, a properly installed standby generator detects the outage within seconds, starts automatically, and restores power to your critical circuits without manual intervention. This system keeps refrigeration running, sump pumps operating, and heating or cooling systems functional during extended outages that can last hours or days across southeastern Michigan.
The installation process involves load calculation to determine which circuits require backup power, selection of a generator sized appropriately for that electrical demand, and integration with your existing electrical panel through an automatic transfer switch that isolates your home from the utility grid during operation. Proper sizing prevents overloading the generator while ensuring it can handle startup surges from motors in appliances like air conditioners and well pumps.
Schedule a property evaluation to assess your backup power requirements and determine the generator capacity needed for your specific electrical loads.
What Proper Generator Installation Requires
Generator installation begins with a detailed load analysis of your home or facility to identify which circuits must remain energized during an outage and calculate the total wattage those systems will draw simultaneously. The transfer switch installation connects between your main electrical panel and the generator, automatically sensing when utility power drops and switching your selected circuits to generator power within ten to fifteen seconds, then reconnecting to utility power once service resumes.
Once the system is operational, you notice that power-dependent systems continue running during outages without requiring you to start equipment manually, flip switches, or connect extension cords. Refrigerators maintain temperature, sump pumps continue removing groundwater, and furnace blowers or air conditioning systems keep operating based on thermostat settings. The automatic operation means backup power activates even when you are away from the property.
Generator systems require annual maintenance including oil changes, filter replacement, and battery checks to verify they will start reliably when needed. MJM Electric Inc provides ongoing service to test system operation, inspect electrical connections at the transfer switch, and address any mechanical or electrical issues before they prevent the generator from functioning during an actual outage.
Questions About Backup Power Systems
Property owners in Shelby Township often ask about generator sizing, fuel types, and maintenance requirements before committing to a backup power system.
What size generator does a typical home require?
Most single-family homes need between 12 and 20 kilowatts depending on square footage and whether you are backing up the entire electrical panel or only essential circuits like heating, refrigeration, and lighting. Load calculation determines the exact capacity required to prevent overloading while handling motor startup currents.
How does the transfer switch know when to activate the generator?
The transfer switch monitors utility voltage continuously and detects when power drops below a threshold or disappears completely, then sends a start signal to the generator and switches your backed-up circuits to generator power once the unit reaches operating voltage and frequency.
What fuel source works best for standby generators in Shelby Township?
Natural gas provides continuous fuel supply without refilling and works well for extended outages, while propane offers an alternative for properties without natural gas service and stores indefinitely without degradation.
How often does a standby generator require maintenance?
Annual service includes oil and filter changes, battery testing, and operational checks to verify the unit starts reliably and the transfer switch operates correctly, similar to maintaining any engine-driven equipment.
What happens if the generator runs out of fuel during an extended outage?
The transfer switch automatically reconnects your home to utility power if it returns, or the system simply shuts down safely until you restore fuel supply, at which point you can restart the generator manually or wait for automatic retry depending on the control settings.
MJM Electric Inc handles generator installations from initial load calculation through final startup and testing. Request a consultation to review your backup power needs and explore generator options suited to your property and budget.
