We need to layout a board to meet UL 935 standard for fluorescent Ballasts. Where can I find the general guidelines to follow (trace spacing, component spacing, etc..)? We will have 270VAC comming in and converting to low voltage 10VDC, less than 1/2 an amp of current.

You did buy the UL document, right?

No, this is a project comming down the pipeline and all resources have not been attained yet, have to go through the usual paper work in line with project time line. I want to be a step a head of the game and just have the general tips for high voltage to work with until the document comes in. As it usually happens in my company, it's going to be late and I'll be "under the gun."

You may also have to get UL 840 "Insulation Coordination Including Clearances and Creepage Distances for Electrical Equipment". it will most likely referenced to by UL 935 and it has PCB spacings.
