* LEGAL DISCLAIMER: The calculators on this page are offered to assist in generating general estimations only, for basic applications. If you are unsure or would like assistance analysing your current situation, feel free to contact MPG with your questions. Please note diesel generator sizing for most applications can be quite complex, with many variables which effect generator sizing. Please contact MPG for professional advice from one of their engineers.

As a guide some of the factors that need to be considered are:

Altitude

Ambient Temperature

Power Factor

Voltage DIP

Motor Start

Starting Method (Direct on Line, Soft Start, Star Delta, etc…)

Non Linear Loads (Harmonic Distortion) – Soft Start, UPS, VFD, etc…
