Panelboards, switchboards and the value line between them

Plate 01

Load centers, panelboards, switchboards

Residential-style load centers and small lighting panels have essentially no resale market. New ones are cheap, and the labor to remove and refurbish a used one exceeds the saving.

Distribution panelboards in the 400 A to 1200 A range start to matter, particularly when they are populated with substantial breakers. Switchboards — free-standing, higher ampacity, often with metering and main breakers — behave much more like switchgear and carry corresponding value.

Plate 02

It is usually about the breakers

The recurring pattern is that a panel's value is the sum of its breakers plus the copper in its bus. A 1200 A panelboard populated with a dozen large molded-case breakers from a discontinued line can be worth several times an identical empty enclosure.

So photograph the interior with the dead front removed if it is safe and permitted to do so, or photograph the panel schedule. Breaker catalog numbers are what determine the offer.

Plate 03

Condition items specific to panels

Water intrusion is the common killer. Panels in mechanical rooms, basements and outdoor NEMA 3R enclosures frequently have corrosion on bus and breaker contacts, which is disqualifying for reuse. Evidence of a fault event — pitted bus, scorched insulation — has the same effect.

Enclosure type matters for the enclosures that do have value: NEMA 4X stainless and specialty enclosures carry their own market independent of what is inside them.

Plate 04

When to sell panels as part of a larger lot

Individually, most panels are not worth a dedicated pickup. As part of a plant electrical lot with switchgear, transformers and MCCs, they add real value because the truck and crew are already there.

This is a general principle worth stating plainly: aggregation is what makes marginal items worth money. Ten panels alone is a logistics problem; ten panels alongside a switchgear line-up is additional revenue on both sides.
