Hiring a plant electrical contractor—questions before you open bids

A short procurement checklist for factory electrical contractors covering surveys, scope clarity, and handover documents.

Plant electrical contracting is judged by downtime risk and standards—not by household wiring speed.

First-round questions

Similar plant experience, site survey before pricing, and whether design and field crews share one accountable channel.

Spell out scope

Main and sub-boards, machine feeders, earthing, lightning, fire alarm interfaces, and temporary works during install.

Close-out

As-built drawings, test records, and a short briefing for the maintenance team should be acceptance conditions.
