To upgrade outdated electrical panels without halting operations, start by assessing your facility’s peak and off-peak hours, scheduling work during low-activity times. Use a phased approach to upgrade sections gradually, ensuring minimal disruption to the overall workflow. Temporary power sources, like generators or backup panels, help maintain uninterrupted power supply during each upgrade phase. Communicate the upgrade plan with staff to keep everyone prepared, and prioritize safety throughout the process. This strategy ensures seamless transitions while keeping your facility operational.

Plan the upgrade carefully to minimize downtime by implementing a phased approach that allows parts of the facility to remain operational during each stage. Conduct an initial assessment to determine the optimal times for upgrades, like off-peak hours or scheduled maintenance windows, to reduce the impact on operations. Set up temporary power solutions where possible, such as portable generators, to support critical systems while panels are being replaced. Communicate the upgrade schedule clearly with all teams to ensure they’re prepared for any temporary changes

I’d start by carefully reviewing the current system to pinpoint limitations and understand load demands at different times. A clear, actionable upgrade plan with specific milestones for each task comes next. To maintain uninterrupted power, phasing in new panels gradually and shifting loads step-by-step will help minimize downtime. All along, detailed documentation and close collaboration with the operations team are essential, after all, it’s a team effort.

Firstly, a thorough assessment of the existing system is critical. This involves identifying the panel's limitations, load capacity, and potential safety hazards. Next, a comprehensive plan is developed, outlining the upgrade scope, timelines, and specific tasks. Redundancy is key: strategically installing new panels in stages, paralleling them with the existing infrastructure, ensures continued power supply. This phased approach allows for the gradual transfer of loads to the new panels, minimizing downtime during each stage. Throughout the process, meticulous documentation and coordination with the operations team are paramount. This includes clear communication about planned outages, alternate power sources.

in my opinion, you should always have a good plan to manage everything within the project, therefore I can suggest that you do a implementation per phases, since you can check that in each moment the project follow the plan and execute activities to solve it just in case that something happens
