Isolated Neutral – Why It Matters
The isolated neutral design keeps the neutral bar insulated from the meter enclosure. This helps ensure that grounding and bonding are handled correctly at the service entrance, reduces the risk of objectionable current on the enclosure, and supports compliance with local electrical codes and utility requirements.

Frequently Asked Questions
Is the Hydel MSC400TW suitable for overhead service?
No. The MSC400TW is designed and approved for underground (U/G) service only. For overhead applications, a different Hydel configuration is required.
What wire size does this meter socket accept?
The conductor range is #6 AWG to 250 MCM copper or aluminum, which covers most standard 200A residential and light commercial service conductors.
Can this meter socket be installed outdoors?
Yes. The enclosure is rated CSA Type 3 / NEMA 3R, making it suitable for outdoor use when installed according to local electrical code and utility requirements.
What does “isolated neutral” mean on this meter socket?
On the Hydel MSC400TW, the isolated neutral means the neutral bar is kept electrically separate from the meter enclosure. The neutral is only bonded where required by code (typically at the main service disconnect), helping electricians achieve a safer, code-compliant installation and avoid unwanted current on the enclosure.
