One Enclosure.
Less Field Work.

Planning a new electrical service?

Our latest blog takes a closer look at why a RONK MSB Meter Socket with Circuit Breaker combo can be a smart alternative to a separate meter base and standalone breaker panel.

By combining utility-grade metering and main disconnect protection in one factory-built enclosure, RONK MSB units help reduce field work, save wall space, limit connection points, simplify ordering, and support code-ready service installations.

Read the full article to learn why the combo approach makes sense for many residential, manufactured housing, temporary power, and light commercial applications.
