Electrical Service Upgrade

A service upgrade involves more than choosing a larger panel. The proposed demand, existing distribution, utility connection and affected equipment need to be considered together.

An engineer may be needed when new equipment or a change in use exceeds the existing design, or when the utility or permit reviewer requests engineering documentation.

Confirm the engineering scope with the professional you engage and any permit requirements with the local building department.

Topics that may be relevant to the review: circuit breaker, panel and subpanel.

The engineer can review existing conditions, evaluate the proposed changes and prepare the calculations or design details included in the agreed scope.

• Increasing capacity for a new business use
• Accommodating equipment beyond the existing design

Start with a short description. These details can help define the scope, but you do not need everything ready to request a quote.

• The project city or county, and the property address if known
• What you want to build, change or repair
• How the space or site is used now and what you plan to change
• Whether you have drawings or photos to share during follow-up
• The status of any permit application and comments received
• Your target dates or other scheduling constraints

• Electrical Engineering
