Grounding information and design guides are presented for use in Arctic design which will comply with the intent and letter of the National Electrical Code (NEC), be economic, and will not result in excessively conservative designs. It is concluded that the proposed grounding practice without a widespread conventional ground grid appears to be adequate and in compliance with the NEC. This method is also cost-effective, resulting in significant savings. Where step and touch potentials are a likely problem, ground planes in the form of grids or platforms are still recommended. A high-resistance ground system is desirable from the point of view of reduced step and touch potentials.<>
