Workshop 240V Outlets and Subpanel Planning for Power Tools

Powering Your Home Workshop

Serious workshop tools demand serious electrical infrastructure. Running table saws, welders, and air compressors on standard household circuits invites tripped breakers and underwhelming performance. Proper planning creates a workshop that actually works.

The 240V Question

Many serious power tools run on 240 volts rather than standard 120V. This includes cabinet table saws, larger air compressors, welders, and some dust collection systems. Planning 240V circuits from the start saves money over adding them later.

Dedicated Circuits for Major Tools

Large motors draw significant startup current. A table saw might run on 15 amps but surge to 30+ amps when starting. Dedicated circuits prevent nuisance trips and ensure tools perform properly.

Subpanel Advantages

Rather than running multiple long circuits from your main panel, a workshop subpanel provides a local distribution point. This simplifies wiring, reduces voltage drop, and makes future expansion easier.

Lighting That Actually Works

Workshop tasks require good lighting. LED shop lights consume little energy while providing bright, even illumination. Position lights to eliminate shadows at primary work areas.

Professional Planning

An electrician experienced with workshop installations understands the unique requirements. They’ll help size circuits appropriately, position outlets conveniently, and ensure your workspace meets code requirements.
