What is one consequence of inadequate load calculations?

Inadequate load calculations can lead to a higher cost for future expansions primarily due to the potential for needing to upgrade the electrical system to accommodate additional loads that were not initially considered. When the original calculations underestimate the demands of the system, it can result in a system that is undersized or not optimized. Future expansions may require substantial upgrades to the infrastructure, including larger transformers, cables, or even complete redesigns of the service entrance to meet the new demands. This reworking is both time-consuming and costly, as it may involve disruptive construction and additional materials that were not planned for in the initial budget. Proper load calculations help ensure that the system is designed to handle current and anticipated future loads, saving on costs related to retrofitting and expansion in the long run.
