Important: Confirm Utility & ESA Acceptance Before Installation

Meter base acceptance can vary by local hydro utility, service type, amperage, overhead/underground entry, isolated neutral requirement, grounding/bonding method, and inspection approach. Always confirm the exact model number, installed configuration, and current requirements with the licensed electrician, local hydro utility, and authority having jurisdiction before installation or energization.

  • Confirm whether the project requires overhead, underground, or combination OH / UG service entry.
  • Confirm whether isolated neutral configuration is required or preferred for the installation.
  • Confirm the exact SKU and accessory requirements before ordering for a utility-facing service project.
What is INK200?

The Hydel INK200 insulated neutral accessory is used with compatible EK series meter sockets where isolated neutral configuration is needed. The final neutral and bonding arrangement must match the project’s service design, utility requirements, and inspection requirements.

Combination OH / UG Design

Suitable for projects where the service entrance may require overhead or underground flexibility, instead of a single-entry-only meter base.

Isolated Neutral Capability

The EK series supports the INK200 insulated neutral accessory, helping contractors configure the meter socket where isolated neutral treatment is required.

Oversize Enclosure

Built with an oversize enclosure and 45° barrel-type connectors, supporting practical field wiring access for service entrance installations.
