FG Wilson Serial & Model Number Guide
Every FG Wilson generator carries a model/serial label. Here is where to find it, what each part of the number means, and how to use it for parts, service and age.
What the number means
Worked example — P200-3:
| Part | Meaning | Detail |
|---|---|---|
P | Engine brand | P denotes the Perkins engine (not “prime”; prime-vs-standby is a separate field on the rating plate). |
200 | Rating (kVA) | The ~200 kVA power class (e.g. P200 ≈ 200 kVA prime / ~220 kVA standby). |
-3 | Series / generation | Build revision of that class — P200-1/-3/-5/-6 coexist as the model is updated (e.g. for a new engine); it is NOT the phase. |
Using the serial number
The FG Wilson model is the kVA class + series; the serial number on the rating plate (on the alternator housing) is the key to the exact build and engine fitted. You do NOT decode the year from the serial — the rating plate prints an explicit “Year of Manufacture”. Quote model + serial for parts.
Common FG Wilson maintenance parts
The service parts FG Wilson's own documents list across more than one generator model. Confirm the number for your unit on its model page or data plate before ordering.
