⚠️ Isolated Neutral Matters in Ontario

On many Ontario jobs, installers are specifically looking for meter bases that support isolated neutral configurations. That is not just a preference issue — neutral bonding in meter bases is a real inspection and safety topic. When an isolated neutral configuration is used, the bonding conductor and service bonding must still be completed correctly in line with code and utility practice.

  • Hydro One’s approved meter-mounting guidance gives preference to isolating the neutral from the meter-mounting device on applicable models.
  • ESA bulletins also warn that isolated-neutral meter bases require the correct bonding conductor arrangement to avoid unsafe installations.
  • This product page is written to help contractors identify the MSC400TW3 quickly when isolated-neutral-ready meter bases are being requested.
Always verify final installation details with the current utility metering guide, OESC requirements, and the inspector or utility having jurisdiction before energization.

🔌 Underground Service Ready

Designed for underground use only, making it suitable for many residential service entrance and meter base replacement applications in Ontario.

🧰 Compression Stud Design

Includes 1/2" line studs for compression-type wire connectors and supports a #6–250 MCM CU/AL load conductor range.

🏗️ Key KO Advantage

The MSC400TW3 differs from the standard MSC400TW by offering 2 x 3" knockouts and a deeper enclosure.
