Meaning of xf in breaker wiring diagram

In a breaker wiring diagram, "XF" is an abbreviation that stands for "Xformer Feed". It refers to the connection point where the primary side of a transformer is connected to the breaker.

In other words, XF indicates the location where the transformer's primary winding is connected to the breaker's busbar or main circuit. This is usually marked on the breaker wiring diagram to help identify the connection point for the transformer.

Here's a breakdown of what XF typically represents:

• X: Transformer (referring to the transformer's primary side)
• F: Feed (indicating the connection point to the breaker's busbar or main circuit)

So, when you see XF marked on a breaker wiring diagram, it's telling you that the transformer's primary side is connected to the breaker at that specific point.
