Electrical Service Upgrades in Glen Burnie, MD
Electrical service upgrades that increase capacity for EV chargers, hot tubs, additions, and modern appliances, including meter base work and BGE coordination.
Service Upgrades
Capacity for Everything You Plan to Add
Service upgrades increase the amount of electrical power your home or business can safely use. Many older homes in Anne Arundel County still have 60-amp or 100-amp service designed for far fewer appliances than families use today. Adding an EV charger, hot tub, swim spa, central air conditioning, an addition, or a finished basement can quickly push older services beyond their limits. Warning signs include breakers that trip frequently, lights that dim when appliances start, a panel with no open spaces, and warm panel covers. A service upgrade, commonly from 100 to 200 amps, replaces the meter base, service entrance conductors, and main panel as needed, and requires coordination with Baltimore Gas and Electric to disconnect and reconnect power. CMB Electrical Services performs service upgrades for homes and businesses in Glen Burnie, Maryland and throughout Anne Arundel County. With 24 years of experience, our licensed and insured team performs load calculations, coordinates permits, inspections, and utility reconnection, and explains expected downtime before work begins.

Capacity for Modern Demands
Service Upgrades Planned for What Comes Next
A service upgrade supports every future project you plan to add. These practices guide every service upgrade we complete across Anne Arundel County.
Load Calculations Before Recommendations
We calculate your existing electrical load and planned additions before recommending service size. Accurate calculations ensure enough capacity for EV chargers, hot tubs, and HVAC without oversizing equipment you do not need. NEC methods guide calculations.
Utility Coordination Handled
Service upgrades require disconnecting and reconnecting power at the meter. We coordinate with Baltimore Gas and Electric and schedule work efficiently, helping minimize how long your home or business is without electricity. Outages stay as short as possible.
Inspections Before Reconnection
Every upgrade requires permits and inspections before power is restored. We handle permitting, coordinate the inspection, and make sure the work is approved and documented so the utility can reconnect service. Utility reconnection follows approval.
Room for Future Circuits
A new 200-amp panel provides open breaker spaces for future projects. Planning for EV charging, generators, additions, or spas now avoids costly rework when those projects arrive in coming years. Generator inlets can be included.
Grounding Brought Up to Date
Older services may have undersized or outdated grounding and bonding. We install proper grounding electrodes and bonding during upgrades, improving safety and protecting the entire electrical system against faults. Proper bonding protects metal piping too.
Downtime Explained Upfront
You will know how long power will be off and when it should return before work begins. Clear communication helps you plan around refrigerators, home offices, medical equipment, or business operations. Refrigerators stay cold for hours.

How it works
How a Service Upgrade Works
Your service upgrades project begins with an on-site evaluation of your existing service size, panel, meter base, grounding, and overall electrical load. We discuss what you plan to add, such as an EV charger, hot tub, swim spa, addition, or central air, and perform a load calculation. During a thorough consultation, we explain your options and provide a free estimate, along with realistic timing for permits and utility coordination. Plans matter.
On upgrade day, CMB Electrical Services coordinates the utility disconnect, replaces the meter base, service entrance, and panel as needed, installs proper grounding, and labels every circuit. We coordinate the inspection and BGE reconnection, then test the system before leaving. If you only need a safer replacement panel rather than more capacity, our panel changes service helps homes throughout Glen Burnie, Maryland and Anne Arundel County. Documentation is provided afterward.
Common questions
Frequently asked questions
How do I know if I need a service upgrade?
Common signs include frequent breaker trips, lights dimming when appliances start, a full panel with no open spaces, warm panel covers, and plans to add an EV charger, hot tub, swim spa, or addition. Warm outlets matter too.
Is 200-amp service enough for most homes?
For most single-family homes, 200-amp service comfortably supports modern appliances, central air, an EV charger, and future additions. Larger homes or multiple high-draw systems may need a load calculation to confirm. Load calculations confirm needs.
Why does a service upgrade involve BGE?
Upgrading service requires disconnecting power at the meter and reconnecting it after new equipment passes inspection. We coordinate with Baltimore Gas and Electric so reconnection happens promptly after approval. Our coordination helps speed reconnection afterward.
What is the typical power downtime during an upgrade?
Most residential service upgrades are completed in one day, with power off for several hours. Timing depends on inspection scheduling and utility reconnection, and we explain expected downtime before work begins. Plan around refrigeration needs.
Do service upgrades require permits?
Yes. Service upgrades require permits and inspections in Anne Arundel County before the utility can restore power. We handle permitting and coordinate inspections as part of the project. County inspection approval always comes before reconnection.
