01

How it differs from an RMU

An outdoor VCB kiosk and a Ring Main Unit may share a voltage class, but they are not interchangeable terms. Their switching functions, feeder arrangements, protection schemes, enclosures and installation requirements must be assessed separately.

02

Installation and interface

Confirm foundation and civil arrangement, access and working clearances, cable entry, control-supply requirements, earthing, site exposure and switching/protection duties.
