- SB2 and SB3 boards with WL insulated case mains bring more than SB1 boards.
- Higher short-circuit ratings (100 and 200 kAIC) add value.
- Copper bus and full distribution sections add value.
- Damaged doors, missing covers or water exposure lower value.
- We do not publish prices. Metal, demand, and condition move them. You get a written number for your unit.
The SB number tells you the capability: SB1 is the compact board up to 2000 A that can sit against a wall, SB2 adds depth and insulated case breakers up to 4000 A, and SB3 is the custom board with rear access and busway or transformer connections. All three are front connected and rear aligned as standard. Siemens connecting kits list SB1 through SB4 and FCI and FCII boards together, which helps when matching parts.

The nameplate
Straight on and readable. Voltage, ratings, model, and serial in frame.
Inside
Doors open: bus, devices, controls, and anything burned or missing.
The whole unit
A wide shot plus what is around it, so we can plan the pick.
The switchboard nameplate is usually on the front of the main section, sometimes inside the door. Shoot it with the voltage, ampacity, short-circuit rating, and series in frame. Then a close shot of each breaker label.
