Power Dist Question

(1/3) > >>

Michael Montag:
Pretty new to the world of Power Distribution.  Recently purchased a line array that comes with an amp rack that has power distribution on board via a 30amp twist lock plug.  My question is what to do when I'm at a smaller venue or park where this is not possible.  What if I only have access to standard 20AMP standard plug circuits?  Is there a safe way to convert this?

There's not a reliably safe way to connect one twist lock to two or more wall outlets.

Doesn't have to be two wall outlets though. Depends how this 'twist lock' is wired.

You can wire a 30A TL connector to a 15A "Edison" cord set, BUT if your system draws more that 15A (or 20A if a 20A plug/circuit) the circuit breaker will function - IT WILL KILL YOUR POWER!  In the middle of a show, it is more than just inconvenient.  I have Crest Pro 9200 amps that came factory wired with 30A TL's.  I used the 30A TL with my distro, but have rented the amps to customers with 15A Edison adapters with no problems, but these customers are never connecting more than a stereo 4 ohm load to the amps. To the best of my knowledge, they have never had any problems.  Even a mid sized line array is another story.

My most recent event with a well know and respected "Red Dirt" act in a 2500 seat arena gave me a chance to measure the current draw during the performance.  I was using 12 DB Tech T12's, 4 T8's, and 6 S30N subs for audio, and 32 LED 100 watt hex wash lights, 8 ADJ PARZ1003K's for spots, 3- 360 watt LED blinders, and a dozen 300 watt LED movers.  The typical draw was just under 20A per leg 120/208 three phase.  This included stage power for the band, but no foggers or haze machines, as per the band's request.  This wasn't a really loud band but typical of country acts.  I was surprised!!!  Much lower that expected!
