You've put M4 bolts in the fuse of a 13A UK plug?!? |

Also, it's not just the ring main capacity, but the contact area and resistance of the plug. A 13A plug has a certain surface area, calculated to safely supply 13A and not 32A. I don't have any UK plugs here, so maybe some volunteer can measuring the contact area for us?
Ceeforms obviously give more contact surface, so safer. I´ve seen a fire destroy a building because the local sparky was a bit lazy and didn't fully tighten up the terminals on the feed he gave us for a gig. The contacts overheated and bang. End of the place. I've also seen a 16A Schuko after a few evenings powering 4 x 1k PAR 64's. Not pretty. Edited by Earplug - 18 February 2017 at 5:18pm |

just because the plug is blue or red and says 63a, doesn't mean the supply's up to it.

We did a relatively big show in the middle of nothing, at a little village. The village has a beautiful 300 years old church, and the major wants to collect some money, to renovate it.
We get the powerdirectly from the central transformer house, which was feed the whole village, 3 phase, 3x63A was the rated power. We used Crest amplification many 8001s for bass, 7001s, and 4601s. Everything was OK during the soundcheck, but when we started the concert we faced with the problem, that all lights in the village was dimming with the beat of the bass. Even the public lights on the street too. All amps are clipped heavily, so I have to turn down the whole system with about 4dB. Sajti |

I installed a 9001 in a venue many years ago. It was wired onto a 32A supply, with something like only 3m of cable, mostly 10mmsq back to the main incomer for the building.
You can get noticable Voltage drops on on supplies in some venues. In another one I used to work in a long time ago, the bass amp would trip out when the fridges turned on and the desk lamp on the mixer used to flash in time to the beat.... In an ideal world, the supply you're connected to wouldn't matter but sometimes on an older installation or one that's not quite been designed/spec'd properly, it can make a difference. Running outdoors, potentially on long feeders (under-sized for the length) I've often watched the Voltmeter on the distro bouncing to the beat, sometimes by an alarming amount.

If it sounds like a gorilla is trying to escape, turn it down.

You can pull 25 amp current for a full non-stop 30 minute period on a proper a 13 amp fuse before it blows. If you need more than that, you need to reconsider your rig setup. Bring more amplifiers, or less rig. |
