Sizing Worksheets
Organize connected load, inrush, ambient temperature, duty cycle and planned expansion before choosing a kVA range.
Prepare a sizing requestTransformer selection without the loose ends
Match primary and secondary voltage, kVA, frequency, insulation class, enclosure, temperature rise and installation constraints before a purchase order reaches the panel shop.

Before the quote
Organize connected load, inrush, ambient temperature, duty cycle and planned expansion before choosing a kVA range.
Prepare a sizing requestConfirm terminal arrangement, tap configuration, grounding provisions and primary-to-secondary connections for the selected catalog number.
Request a drawingCompare electrical ratings, enclosure details, dimensions and mounting rather than substituting from horsepower or kVA alone.
Submit an existing partSelection checkpoints
A nameplate match is only the start. Our review path accounts for the physical and electrical interfaces that determine whether a transformer can be installed, wired and operated as intended.
Connection arrangement and available taps are checked against the source and utilization equipment.
Continuous demand, motor starting and nonlinear loads inform capacity and temperature-rise choices.
Rated frequency and operating profile remain explicit in the request record.
Ventilation, ingress exposure and clearance requirements are evaluated with installation conditions.
Bring the real project data
Send the existing catalog number, single-line diagram, load schedule or nameplate photo. The response will identify assumptions, open questions and the series-level documents needed for approval.
