We can visit with your team to make specific recommendations, but the basic rule-of-thumb is to size your transformers to operate at 80% of their expected load capacity (also known as kVA). In other words, the general rule-of-thumb is to choose a transformer kVA around 120% of your expected load. This provides a 20% margin to account for ...
