I've been working for a retailer for a few years on electrical odd jobs. Most of the time it involves replacing circuit breakers. It is a commercial store front that sells running shoes. Apparently, when it was built the lighting circuitry was designed to turn on/off with breakers only. The breakers are failing regularly and I'm feeling guilty charging him $80 a visit to replace a breaker. One solution would be to install a light switch below the panel and just re-route the wires. Any other suggestions?

Thanks,
Byron
