Frequently asked

Three things people ask first.

Is Main Switchboard (MSB) data free?

Yes. Every model page, every guide and every datasheet for this type is readable without an account. An account adds saved searches and requests, nothing is taken away.

My model is missing — what now?

Send us the nameplate. We identify it by hand, add it to the library, and if you need a part or a service, the request is already on our desk.

Can you source a Main Switchboard (MSB) part?

Yes. Tell us the manufacturer, the model and what you need — a person reads every request and replies by e-mail.
