ASHRAE/IESNA 90.1 and the IECC energy efficiency codes aren't the only codes lighting designers must be aware of. Lighting designers must also be familiar with the NEC (National Electrical Code), the CEC (Canadian Electrical Code), or whatever electrical code is in force in the region where the design is to be installed. To complicate the situation, lighting designers must have a working knowledge of the applicable safety standards that prevail for the products they specify. In the U.S., ANSI/ UL safety standards are used to determine whether a product is compliant or not, and eligible to bear an NRTL (Nationally Recognized Testing Laboratory) "Listed" mark. Failure to adhere to the applicable electrical code and safety standards will result in an unsuccessful project which will impact your reputation and your bottom line since you will be forced to spend valuable time trying to remove a violation (red flag) issued by an electrical inspector.
