This is placeholder draft content. It will be replaced with a full article once written — for now it exists so the blog layout has real text to render.

Residential and commercial electrical work draw on the same core skills, but the scale, code requirements, and planning involved are quite different.

Key differences

  • Higher electrical loads and three-phase power in commercial spaces
  • Stricter code and inspection requirements for business properties
  • Work often scheduled around business hours to limit downtime
  • Different lighting, panel, and circuit needs at scale

Whether it's a single-family home or a multi-unit commercial build-out, the goal is the same: a safe, code-compliant electrical system built for how the space is actually used.
