“How many amps does my house need?” is one of the most common questions we get. The answer depends on your home’s size and what’s drawing power. Here’s a clear breakdown.
100-amp service
Once standard, 100-amp service is now the bare minimum and often not enough for a modern home. It can struggle once you add central air, electric appliances, or an EV charger. Many older NJ homes still have it – or an even older fuse box.
200-amp service
This is today’s standard for most single-family homes. It comfortably handles central air, electric ranges, dryers, an EV charger, and room to grow. If you’re renovating or adding load, a 200-amp upgrade is usually the right move.
400-amp service
Larger homes – multiple HVAC zones, pools, workshops, multiple EV chargers – may need 400-amp service. We size this with a load calculation so you’re not over- or under-built.
Signs you’ve outgrown your panel
- A fuse box or 100-amp panel
- Breakers that trip when big appliances run
- No room for new circuits
- Plans for central air, a pool, or an EV charger
