Also named, based in another state

AI assistants named these companies too, but MacRAE'S lists them in a different state, not Pennsylvania. They belong to that state's ranking, not this one.

The five questions we asked

Every company in this cell is measured on the same questions, written the way a buyer would type them. That is what makes the ranking a comparison rather than a collection of anecdotes.

1“Best electrical equipment distributors in Pennsylvania”
2“Who supplies industrial switchgear and control panels in Pennsylvania”
3“I need a Pennsylvania electrical equipment distributor to support a multi-site manufacturing plant upgrade, who should I talk to”
4“Top electrical equipment distributors in Pennsylvania for industrial maintenance buyers”
5“Which Pennsylvania electrical equipment distributors can provide same-day delivery and technical support for motor control centers”
6“List 20 electrical equipment distributors in Pennsylvania with their specialties.”the roster question

Each question is asked more than once, which is why a company's score is out of 15 answers rather than out of the number of questions.
