Transformer FAQs

Get answers to common questions about selecting and installing transformers.

To size a control transformer, calculate the total VA (volt-amperes) load of connected components and apply the 80% loading rule to ensure continuous operation. Always round up to the nearest available size.

A buck-boost transformer offers an affordable solution for small voltage corrections, which are ideal when you need to adjust incoming voltage by 5-20%. These units are compact, efficient, and cost less than larger isolation or control transformers.

Yes. OSHA and NEC require a means of disconnect for transformer maintenance and lock-out/tag-out compliance. Consider pairing your transformer with a proper disconnect switch to stay compliant and safe.
