Designing location for a large UPS (250 kVA) Nominal 208 V service meeting Condition 2 (grounded cabinets behind live parts access). Since Voltage Phase to Ground is only 120 V, does this require 36-inch or 42-inch clearance? (Sorry if this is an old question. New to Forum and haven't learned yet how to search 1,000 pages.)
