What Affects the Cost in NJ?
These are the key factors that will determine your actual project cost in Central NJ.
Current vs. Target Amperage
Most NJ homes need at least 200A for modern loads (EV chargers, HVAC, induction ranges). Some older NJ homes still have 60–100A service that's inadequate and potentially unsafe.
Meter & Service Entrance
If the utility meter socket or service entrance cable also needs upgrading, add $500–$1,500. JCP&L and PSE&G may need to disconnect power, which adds scheduling time.
Additional Circuits
Adding dedicated circuits for HVAC, ranges, or dryers at the same time saves money vs. separate trips. Budget $150–$350 per new circuit.
Permits & Inspection
NJ requires permits for all panel work. The inspector must approve before power is restored. Budget $300–$600 for permits; your licensed electrician handles the filing.
Home Age
Older NJ homes (pre-1970) may have knob-and-tube or aluminum wiring that must be addressed simultaneously. This can significantly increase total project cost.
