I had spoken out at one time that a transformer was centertapped and grounded to keep the voltages to ground at a safer level and was jumped on like a pack of wolves that this was untrue and where did I see this and what book was I referencing. Well today is the day that I found it and the book that it is referenced in is the OSHA Standards for the construction Industry (29 CFR PART 1926) With Amendments as of January 2006. The definition of this standard is from the Occupational SAFETY and Health Administration. Subpart K Electrical 1926.404(f)(1)(iv)(A) STATES>>If the system can be so grounded that the maximum voltage to ground on the ungrounded conductors does not exceed 150 volts; .............I knew I would find it This is an electrical safety requirement handed down from the federal government and it is also the law. Lets see if the same wolves have something to say about this. I knew I would find it.
