Problems It Solves

An outage costs more per hour than the set itself.

How It Compares

Compared with	What to consider
A rebuilt or used engine of the same rating	A rebuilt unit may show the same 312.5 kVA on paper, but its running history is unknown and the warranty rarely covers the whole engine.
A larger engine in the same NTA855 range	Moving up a frame size adds weight, envelope and fuel burn; specify the next size up only if the duty cycle really needs the headroom.
A non-Cummins engine of similar output	Parts and service for Cummins families are available in most markets, which matters more over ten years than the purchase price on day one.
