Welcome to the . . 


We here at Bellah's Custom Homes know that with every hour the power is out for a business, the losses mount. But a reliable, affordable standby power system from Cummins can prevent those losses and let your customers stay open for business, or just enjoy the convenience of power in your own home in the event of a power outage. Whether you are looking for generators, automatic transfer switches, paralleling switchgear, or a complete integrated power generation system, finding the best power solution takes a relationship with someone who understands your challenges the way you do. With Bellah’s Custom Homes we’ve got a certified technician ready to deliver everything from complete project design to generator maintenance and service. Cummins is known for rugged, reliable power systems. These systems are now even more customer-friendly in a line of affordable, preconfigured generators for light commercial and residential applications.

Note: You should not attempt to specify and install a power system on your own. Electrical connections must be made and fuel systems installed by qualified and licensed personnel. Improper installations present hazards, which can result in personal injury or property damage. Please contact a licensed residential electrician and your local natural gas or propane supplier for these services. In all cases, you should contract a Cummins Onan Dealer and/or certified technicians.
