Meter Isolator Switches & Changeover Switches

Shop meter isolator switches, meter-tail isolators and changeover switches for trade installations, including 100A double-pole and enclosed options.

Meter isolation and source changeover perform different functions. Select the device around its intended switching duty, supply arrangement, current rating, poles and enclosure requirements.

Quick guide: A meter isolator provides a local means of isolating the installation downstream of the meter. A changeover switch transfers a load between designated supplies and must be specified for that switching arrangement.

  • Meter isolators: local switching between the meter position and downstream installation
  • 100A double-pole options: line and neutral switching for compatible single-phase supplies
  • Enclosed isolators: ready-housed switching devices
  • Changeover switches: controlled transfer between defined supply sources

Meter Isolation and Supply Changeover

Confirm who owns and may operate equipment at the intake position before work begins. The isolator or changeover device must suit the supply, current, switching category, conductor arrangement and enclosure. Installation should follow the network, meter operator and manufacturer requirements that apply.

Meter Isolator Switches

Provide a defined local point of isolation downstream of the metering equipment where the installation arrangement permits. Check rating, poles, terminals and ownership boundaries.

Enclosed Meter-Tail Isolation

An enclosed device can provide a complete housing for local switching. Confirm cable entry, terminal capacity, IP rating and mounting space.

Changeover Switches

Used to transfer a load between intended sources. Specify the device for the supply arrangement and ensure the design prevents unsafe source interaction.

Specification Checklist

  • Purpose: distinguish simple isolation from source changeover.
  • Supply: confirm phase arrangement, poles, neutral switching and rated current.
  • Terminals: check conductor capacity and meter-tail entry.
  • Enclosure: verify mounting position, protection and accessibility.
  • Authority: follow the requirements of the relevant network and metering parties.
