I taken the Delaware exam last week and one question stump me and I was wondering if someone could help. The question appeared vague and not enough detail.

The question was:
A switch operates a lighting transformer, what is the rating of the switch?
The multiply choices for the question were:
1.5, 2, 2.5 or 3.

I look under Switches Art 404 and Transformer Art 450 but I couldn't find ratings of a switch for a lighting transformer.

As I mention the question was vague and I wasn't sure if they are looking for a switch operating a large transformer or a switch operating a small low lighting transformer.

Any help thanks! GoNEC
