/ Why we write these

Written for the person who has to approve the invoice.

Most electrical content online is written to rank, not to be used. These are not that. Each one comes out of a job we ran in Duval, Clay, St. Johns, or Nassau — what the scan found, what the utility required, what the sizing calculation actually returned, and where the number on a competing proposal came from.

They are written for facility directors, property managers, and GCs: people who do not need to be sold on a service but do need enough of the mechanism to make a defensible decision. If an article saves you from ordering the wrong generator, it did its job whether or not you call us.
