You're asking a good question with historical context! Here's a breakdown of whether a POCO meter can be used as a disconnecting means and the regulations around it

The Short Answer:

Generally, the POCO meter cannot be considered the service disconnecting means according to current electrical codes (NEC in the US). While this was permitted in some areas and under specific circumstances in the past, it's no longer standard practice, and is often explicitly prohibited or strongly discouraged.

Why It's Not Allowed (Generally)



Safety

The primary reason is safety. Utility personnel (POCO - Power Company) need to be able to disconnect power before the meter in emergencies or for maintenance. Relying on the meter as the disconnect puts them at risk, especially if the meter or its connections are faulty. It also means the homeowner or electrician can't easily de-energize the entire electrical system for maintenance or safety reasons.

Accessibility

The disconnecting means needs to be readily accessible to the homeowner/electrician, so that they can de-energize the premises. The utility meter may not be easily accessible to the homeowner.

Control

POCOs want to maintain control over their metering equipment. Allowing a homeowner or electrician to routinely disconnect/reconnect power at the meter could lead to tampering, damage, or safety hazards.

NEC Requirements

The National Electrical Code (NEC) requires a readily accessible service disconnecting means at a specific location, usually near the point where the service conductors enter the building (e.g., outside, in a readily accessible location inside near the point of entry). The NEC specifically addresses the requirements for service disconnects, and the meter typically doesn't meet those requirements.

Historical Context and Exceptions



Older Installations

In some older homes, particularly in the past, the meter socket itself might have been used as the disconnecting means. This was more common in smaller homes with limited electrical loads. The electrician would pull the meter to de-energize the system. This is often grandfathered in (meaning it's allowed to remain as is as long as the system isn't significantly altered), but it's not a compliant installation under current codes.

Specific POCO Agreements

Historically, some utilities allowed, or even required, the meter socket to act as the disconnect. This was often based on local regulations or specific agreements between the utility and the homeowner. These cases are becoming increasingly rare.

Combination Meter/Disconnect

A device exists that combines the meter and the disconnect in a single enclosure. However, these must be specifically designed and approved for this purpose, and the disconnect mechanism must be readily accessible and clearly labeled.

Current Requirements (Typical)


Service Disconnecting Means

A readily accessible service disconnect (typically a circuit breaker or fused switch) must be installed before the meter. This allows power to the entire house to be shut off easily and safely. The rating of the disconnect must be adequate for the calculated service load.2.

Location

This disconnect must be located in a readily accessible location, typically near the point where the service conductors enter the building. It must be permanently marked as the service disconnecting means.

Important Considerations



Local Codes and Utility Regulations

Always check with your local electrical inspector and your local utility company (POCO) for their specific requirements. They have the final say on what is allowed in your area. Utility requirements often supersede general electrical codes.

Safety First

Never tamper with the meter or attempt to disconnect power at the meter without explicit authorization from the utility. This can be extremely dangerous and could result in serious injury or death.

Modernization

If you have an older installation where the meter socket is used as the disconnect, consider upgrading to a modern service entrance with a dedicated disconnect for safety and code compliance.

In Summary:

While there might be a historical precedent or very rare exceptions, the POCO meter should not be considered the primary service disconnecting means. A dedicated, readily accessible disconnect is required by modern electrical codes and is essential for safety. Always consult with your local authorities (inspector and utility company) to ensure compliance. Flag for review
