Main Electric Service Panel
[ad#block]Electrical Question: What amperage size main panel should I install for my home and the electrical circuits?
- Is a 100 amp electric service panel big enough for my house?
- My house will have the following electrical devices:
- 220 Volt Stove.
- 220 Volt Dryer.
- 220 Volt Well Pump.
- 220 Volt Hot Tub.
- Plus all the other 110 appliances.

Thanks for your electrical question Tom.
How to Size an Electrical Panel for a Home
Application: Main Electrical Panel.
Skill Level: Intermediate to Advanced – Best performed by a Certified Electrician or Electrical Contractor.
Tools Required: Basic Electricians Pouch Hand Tools and Voltage Tester.
Estimated Time: Depends on personal level experience and ability to work with tools.
Precaution: Identify the circuit, turn it OFF and Tag it with a Note before working with the wiring.
Important: Burnt or damaged wiring and circuit components should be replaced with new electrical materials of the same voltage and amperage rating.
Notice: Installing or Rewiring Home Electrical Wiring should be done according to local and national electrical codes and installing new or replacement electrical parts or equipment may require to have a permit and be inspected.
Considerations When Sizing a Main Electrical Panel
- The size of an electrical panel for a home is based upon several factors, one of which is the size of the home, which is generally expressed in square feet of the floor space in the occupied or living area.
- Based upon the devices described in this question you would need to install a panel larger than 100 amps to handle all these 220 volt electrical circuit loads.
- A listing of all the electrical loads with the voltage and the amperage will be required in order to determine the total connected load.
