Electrical Service Requirements



Service per Building

Typically, one electrical service is provided for the entire building.

Disconnects per Service

Code requirements vary depending on jurisdiction, but generally, there are six disconnects allowed per service.

Renovation Considerations



Number of Occupancies

With six occupancies, you will exceed the typical six disconnects per service allowed.

Historical Building

The age and historical significance of the building may impact the available electrical infrastructure.

Possible Solutions



1. Additional Service

Add a second electrical service to accommodate the additional disconnects required. This may require additional trenching, conduit, and equipment upgrades. Generally, the most straightforward solution but can be costly if extensive infrastructure upgrades are needed.

2. Subpanels

Install subpanels within the building to distribute power from the main service. Each subpanel would have its own disconnect, allowing for more than six disconnects per service. Subpanels must be properly sized and located to meet code requirements.

Recommendations

1. Consult with a licensed electrician to evaluate the existing electrical infrastructure and determine the best solution.
2. Consider the historical significance of the building and work with architects and historic preservationists to ensure the renovation respects its character.3. Plan for future expansion and flexibility by installing an electrical infrastructure that can accommodate potential growth.

Additional Considerations



Electrical Demand

Calculate the electrical demand for all occupancies to ensure the service capacity is adequate.

Voltage and Phase

Determine if 208Y/120 is the appropriate voltage and phase configuration for the building's needs.*

Code Compliance: Ensure that the electrical installation complies with all applicable codes and regulations. Flag for review
