Hello all... I am new on this message board. I have a hopefully simple question. I need to replace the buss bar unit in my Challenger SB20 (200 amp) home disconnect panel. I have searched for individual parts, complete panels and have found nothing. Is this company STILL in business? Does anyone know where I can get parts/complete? I really hate to think about changing out to a new different brand panel... Any HELP? Email me please! Thanks Doug in Ohio:confused:

Challenger has gone away, some new and replacement breakers are still available .

Try doing a search for Challenger panelboards, there are some surplus companies than may have what your looking for.

I am afraid you may need to replace the panel.
