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