Adding power to a shed transforms it from simple storage into a functional workspace. With electricity, you can add lighting, outlets for power tools, and even heating and cooling.
But running power to a detached structure involves trenching, underground conduit, grounding, and installing a subpanel. From determining how many volts and amps fit your needs to whether the existing electrical service can provide them to digging a code-compliant trench for conduit, powering an outbuilding is typically best handled by a licensed electrician.
