Project capacity guide
Do you need 200 amps for an electric dryer?
Electrical-capacity planning for an electric dryer at home.
Short answer
An electric dryer does not automatically require 200A service. The decision depends on dryer rating, existing fuel changes, panel space and the home’s other electric loads.
Key takeaways
01Start with equipment specifications and the home’s current demand.
02Panel space does not prove service capacity.
03The project should be assessed before equipment is purchased or installation is booked.
What determines capacity
The contractor needs to review dryer rating, existing fuel changes, panel space and the home’s other electric loads. The applicable calculation and local permit rules determine the acceptable design.
Alternatives to a service increase
the existing service may remain when the full demand supports it. Any alternative still needs to be approved for the equipment, installation and jurisdiction.
What to prepare
Bring the equipment model or expected rating, service-size clues, existing major loads, panel-space information and future project plans.
Field notes / decision evidence
Check what the laundry change adds
A dryer conversion involves the appliance, circuit route and combined household demand.
Appliance specification
Bring the chosen dryer's electrical requirements and identify whether the existing dryer is gas or electric.
Circuit and location
Ask whether an appropriate circuit exists at the laundry location or whether new wiring and finished-surface repair are part of the quote.
Combined plan
Include any planned electric water heater, heating system or EV charger in the same capacity assessment.
Illustrative scenarioExample only: changing a gas dryer to electric is a different load change from replacing an existing electric dryer with a comparable model.

Questions
Frequently asked
Can a 100A home support an electric dryer?
Sometimes. The service size alone cannot answer; existing demand and project design matter.
What should I do next?
Use the Capacity Check to organize what you know, then have a qualified electrical contractor complete the assessment required for the property and jurisdiction.
