Okay, thanks for the clarification. With 2P-600A fuses, you're dealing with a substantial service. And you are correct, you can't feed a meter bank with 10 x 100A circuit breakers from those fuses. Here's why, and what you likely need

Why it won't work:
Ampacity Imbalance

Ten 100A breakers potentially draw 1000A total (10 x 100A). While unlikely all breakers will simultaneously draw their full rating, electrical codes require you to account for that potential, and more importantly, the actual load calculation. 600A fuses will overload and blow long before that potential is reached.

Code Violations

Electrical codes (like the NEC in the US) severely restrict exceeding the ampacity of the service equipment (fuses, conductors).

What you likely need (General Guidance - Consult a Qualified Electrician)

Given the 600A service and the need for 10 individual services with 100A breakers, here's a possible approach.

This is a general outline. A licensed electrician must perform the necessary calculations and design the actual system to meet local codes and load requirements.1. Load Calculation is Critical

Before anything else, you must perform a detailed load calculation for each of the 10 meters. You need to determine the actual anticipated maximum demand load for each tenant. 100A breakers may be overkill; a smaller breaker size may be sufficient, reducing the overall service demand.2.

Metering Equipment



Meter Bank

You need a proper meter bank enclosure designed for multi-tenant metering. These enclosures are designed to accept a common feed and distribute power to individual meter sockets.

Individual Meter Sockets

Within the meter bank, you'll have individual meter sockets where the utility company will install the meters.3.

Sub-panels

Each meter socket will feed a dedicated sub-panel.4.

Protection and Distribution



From the Fuses to the Meter Bank

The 600A fuses likely protect the main conductors feeding the meter bank enclosure. The conductor size must be properly sized for the 600A protection.

Main Breaker (Optional)

Some meter bank configurations include a main breaker within the enclosure after the meter and before the individual tenant sub-panels. This is optional, but it provides an additional layer of protection. This main breaker must be sized to protect the entire meter bank.

Feeders to Sub-panels

From the meter bank, individual sets of conductors will run to each tenant's sub-panel.

Sub-panel Main Breakers

Each sub-panel will have a main breaker (typically 100A in your example, but potentially smaller after the load calculations).

Branch Circuits

Within each sub-panel, individual branch circuits (15A, 20A, etc.) will be wired to power the tenant's loads (lights, outlets, appliances, etc.).

Important Considerations



Diversity Factor

This is a key concept. The diversity factor acknowledges that not all 10 tenants will be drawing their maximum potential load simultaneously. This factor is used in load calculations to reduce the overall service size required.

Service Size Upgrade

After doing the load calculations with the diversity factor applied it may be possible to make the 10 services work with the 600A.

Local Codes and Utility Requirements

Your local electrical codes and the utility company's requirements will dictate exactly how the service must be designed and installed. They will likely need to approve the design.*

Professional Electrician is a MUST

This is not a DIY project. It requires the expertise of a licensed, qualified electrician experienced in multi-tenant metering systems. They will perform the necessary calculations, select the appropriate equipment, and ensure the installation meets all applicable codes.

In summary: You'll need a properly designed meter bank system with appropriately sized conductors, sub-panels, and overcurrent protection for each tenant, based on a professional load calculation. Consult with a licensed electrician to design and install the system. Don't attempt this work yourself if you're not a qualified professional. Electrical work can be dangerous and can result in fire or electrocution if done incorrectly. Flag for review
