Description
Hydel EK400RO 200A Combination Meter Socket with Isolated Neutral Capability, 4 Jaw, Oversize Enclosure
The Hydel EK400RO is a 200 amp, 600 volt, 4-jaw combination overhead/underground meter socket designed for utility-facing residential and light commercial service entrance projects. It features an oversize enclosure, barrel-type line connectors angled at 45°, and a No. 6–250 MCM CU/AL conductor range. For Ontario installations where isolated neutral configuration is preferred or required, the EK series supports the Hydel INK200 insulated neutral accessory.
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.
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.
