Re: Convert a dedicated 50 Amp GFCI Breaker - to an outlet - for a wedding!
If there is no neutral wire going to the hot tub panel where the GFCI breaker is, this is a no-go. A neutral wire will be REQUIRED. Stop here.
Find out from the DJ what his power requirements are, specifically the voltages (120V only or 120/240V), amperage, and what style of plug his power distribution unit (called a "distro" in trade lingo) uses. Quite often this is a NEMA 14-50 "range plug", but check to be sure.
If his distro uses 120/240V power (BOTH voltages) then you may be able to install an appropriate receptacle for his use. If his distro is rated for LESS than 50A, you'll need to install a breaker of appropriate amperage.
The GFCI may be a problem. Stage and sound equipment, especially when installed outdoors, SHOULD be protected by GFCI. The problem is that some older equipment (especially tube-type guitar amps) may have voltage leaks to ground which, taken by themselves are safe and won't trip a GFCI. But if you have several pieces of such equipment, it can add up to leakage currents that are enough to trip a single GFCI. So rather than a single upstream GFCI, many sound providers have individual GFCIs in their distros or stage power stringers, so that the people are protected from shock but also to avoid nuisance tripping from cumulative losses. You might need to replace the GFCI breaker with a non-GFCI breaker, as long as the distro or stringer has GFCI protection.
If he only needs 120V power, then you might remove the 50A GFCI breaker and replace with a pair of 20A single pole GFCI breakers and wire them to standard 120V receptacles.
The fact that you're asking this suggests that you don't have a lot of experience with more complex electrical situations. I highly recommend contacting an electrician to perform the work.

The "Senior Member" designation under my name doesn't mean I know a lot, it just means I talk a lot.I've been a DIYer since I was 12 (thanks, Dad!). I have read several books on various home improvement topics. I do not have any current code books I can refer to. I was an apprentice plumber for two years.
