Big Homes, Bigger Loads: Is Your Panel Keeping Up?
Many homes in Lower Merion Township were built generations ago and then expanded more than once. Owners enlarged kitchens, added wings, put in central air and finished basements. Each change added load, but the original panel often stayed. That is how you end up with breakers that trip when two air handlers run together, or a garage that loses power whenever the dryer runs. Lower Merion homes also tend to have more specialty loads, like induction ranges, wine coolers, pool equipment, heated floors and EV chargers. A panel that handled the house twenty years ago may be near its limit today. Warning signs include warm breakers, crowded panels full of tandem breakers, and lights that dim when large equipment starts.
Common in Lower Merion Homes
- Multiple AC zones on one service
- Additions fed from the old panel
- Crowded panels with tandem breakers
- Pool and spa equipment loads
- EV chargers added later
How We Do It
Panels, Subpanels and Township Permits Done Right
Bigger homes often need a smarter layout, not just a bigger panel. We start with a full load calculation, then decide whether a 200 amp upgrade, a larger service or added subpanels makes the most sense. A subpanel near a new wing, a carriage house or a finished basement cuts long circuit runs and gives you breakers where you need them. Lower Merion Township handles permits for electrical work here, and we file and schedule everything with the township. We hold City of Philadelphia electrical contractor license #37352, and our team includes an ICC Certified Commercial Electrical Inspector who checks the work against the code before the township inspector arrives. We coordinate any service disconnect with PECO, so you only plan for one shutoff.
How We Plan It
- Whole-house load calculation
- Main panel and subpanel layout
- Township permit filed for you
- PECO shutoff coordinated
- Code check before inspection
Why It Pays Off
Plan for the House You Will Have in Five Years
Many Lower Merion homeowners upgrade in stages: a kitchen this year, a heat pump next year, two EV chargers after that. If each project adds its own patch to the panel, you end up with a crowded, confusing setup that is hard to service. A planned upgrade avoids that. We size the main panel and subpanels for the projects on your list, leave space for future breakers, and label everything clearly. When you sell, a clean, well-documented electrical system answers the questions buyers and inspectors ask about large older homes. Tell Electrical Hazards, Inc. what you are planning, and we will build a panel layout that grows with your home instead of holding it back.
Projects Worth Planning For
- Kitchen and addition remodels
- Heat pump conversions
- Two-car EV charging
- Pools, spas and outdoor kitchens
- Carriage house or guest suite power

FAQ
Frequently Asked Questions
Who handles electrical permits in Lower Merion?
Lower Merion Township. We file the permit, schedule the inspection and meet the township inspector at your home.
Do I need a bigger service or a subpanel?
It depends on your load calculation and where the loads sit. Often a 200 amp main panel plus a well-placed subpanel works better than one oversized panel.
Can you upgrade without disturbing finished walls?
In most cases, yes. We plan routes through basements, attics and utility spaces and keep wall openings to a minimum.
Can my panel handle two EV chargers?
Maybe. We check your load calculation and can use load management or a service upgrade so both cars charge safely.
Do you work on older homes with additions?
Yes. Mixed old and new wiring is common here. We check each part of the system and tie it together safely.
