Questions recently have been raised regarding GFCI protection for temporary power sources – especially, "Is GFCI protection required only for utility-supplied power, or is it also required for power supplied by on-site generators?" The answer: both situations require GFCI protection, according to Section 590.6 of the National Electrical Code.*
