What information do I need to request switchgear?

Send as much technical information as you know. A one-line diagram, shop drawings, nameplate photos, old quote, or equipment photos can be enough to begin — voltage class, bus rating, and configuration are helpful but not required.

Can GridGear source medium-voltage switchgear?

Yes. We source medium-voltage metal-clad and metal-enclosed switchgear, padmount distribution gear, and related lineups across common voltage classes.

Can GridGear help find replacement breakers?

Yes. We help locate replacement MV breakers and compatible components when a full lineup is not required or when breakers are the critical missing piece.

What if I need gear to match an existing lineup?

Note the existing manufacturer and model in your request. Matching existing gear is often possible but depends on availability. Upload photos and drawings of the existing lineup when available.

Can GridGear coordinate inspection, testing, freight, or logistics?

Yes. We coordinate third-party inspection, breaker testing, freight, and rigging through qualified partners to support a higher-confidence transaction.

Switchgear Sourcing

Medium-voltage switchgear, transfer equipment, and electrical lineups when factory lead times or matching existing gear is the problem.

GridGear helps procurement teams locate medium-voltage and large low-voltage switchgear when a new factory order will not meet the schedule, specified gear is obsolete, or a replacement has to match voltage, bus rating, interrupting rating, breaker type, or lineup configuration. We also source generator paralleling gear, automatic transfer switches, and transfer switchgear for backup-power and data-center applications.
