Hello Gentlemen,
I am putting together a temporary power system for some vendors at a week long sporting event, there will be 6 food vendors and a maximum of 20 non-food vendors. I will be setting up a temporary sub-panel and feeding MWBC's with 12/4 hard usage cord(SOOW or similar) on two pole breakers. Food vendors will be getting two circuits each in a 2G box and the other vendors will be sharing a circuit between two, each with their own 1G box(4 boxes per run, last two fed with 12/3).
All of the non-food vendors will be provided circuits with GFCI protection, for the food vendors I am on the fence about providing GFEP to avoid nuisance trips. I see 590.6 regarding ground fault protection for personnel in temporary installations but if the food receptacles are deemed for equipment(appliances) could I use GFEP breakers and standard duplex receptacles? My estimate has been padded to allow for the expense of GFEP breakers.
The safest and most reliable way I see this being done for personnel is to stack the panel with GFCI breakers and deal with the nuisance trips, I'm just worried we'll have some extremely angry food vendors if their circuits trip multiple times a day for a week even if we have a rep on site to address any power issues.
What do you guys think?
