Generators in Anne Arundel County
Residential Backup Power Planned Around Your Home’s Essential Systems
A power outage can interrupt heating, cooling, refrigeration, lighting, water systems, security equipment, and other essentials. A carefully planned backup generator can keep selected systems operating until utility service returns.
A standby generator connects permanently to the home’s electrical system, eliminating the manual setup required for a portable unit. A professional assessment considers what must stay powered, the home’s electrical demand, and the conditions that will shape the installation.
Discuss your backup power needs with CroppMetcalfe Linthicum Heights. Call (410) 824-5809 to request generator service for your home.

Our experience with electrical, heating, cooling, and other home systems gives us a broader view of backup power planning. We consider how the equipment and functions your household depends on can work together during an outage.
Our technicians are licensed, bonded, insured, and ACE certified, and our work is backed by the Service Experts Guarantee. Our website also features customer feedback describing generator maintenance completed by a technician from CroppMetcalfe Linthicum Heights.
From Electrical Loads to Final System Testing
Generator sizing begins with deciding what you need to operate. Essential-circuit backup may prioritize refrigeration, lighting, a sump pump, and selected heating or cooling equipment. Whole-home backup requires a broader review of electrical demand.
A residential generator project should address:
- Electrical loads: The starting and running demands of the systems and appliances selected for backup power.
- Electrical equipment: The panel, wiring, transfer equipment, and load management controls used to prioritize circuits.
- Installation conditions: Available fuel, equipment placement, clearances, service access, permitting, and inspection requirements.
- System operation: Testing, automatic operation, monitoring, safe use, and ongoing maintenance.
An automatic transfer switch isolates the home from utility power before directing generator power to selected circuits or the broader electrical system. The right generator, transfer equipment, and installation design depend on the property, so an evaluation is necessary before determining whether a system can power the entire home.
Preparing for Local Weather-Related Outages
Anne Arundel County identifies winter storms, severe thunderstorms, hurricanes, flooding, extreme cold, and extreme heat among the hazards that can interrupt power. County emergency management guidance recommends considering a backup power source and following proper installation, placement, operation, and maintenance practices.
Before choosing a system, identify the loads that matter most during an extended outage. These may include heating or cooling equipment, refrigerators, water systems, sump pumps, medical equipment, internet hardware, and security devices. This list provides a practical starting point for comparing essential-load coverage with whole-home backup power.
Safety must be part of the plan. Proper outdoor placement can reduce exhaust and moisture risks, while transfer equipment helps prevent dangerous backfeeding into utility lines.

Efficiency can be improved by using energy-efficient appliances and light bulbs, adding insulation to walls and attics, and sealing air leaks.
-
Signs of electrical service issues include flickering lights, frequent circuit breaker trips, hot or discolored electrical outlets or switches, buzzing sounds from outlets or switches, and burning smells. Another issue is improper outlets in the kitchen or bathroom – which should be GFCI (ground fault circuit interrupter) outlets. This is a shock-resistant outlet that acts as a safety measure and helps prevent fire hazards since water is a great conductor of electricity.
-
It is recommended that electrical service be inspected at least every 10 years to ensure that it is safe and up to code.
-
Some safety precautions include turning off the power supply before working on any electrical component, using insulated tools, wearing appropriate personal protective equipment (PPE), and following electrical codes and regulations.
