3 Phase Power Outlets - ControlBooth
2006年5月15日 · I think my question has been answered in that a 20amp 3 phase plug is smaller than a "standard" 3 phase plug, but all 3 phase socket (regardless of rating) is the same size. I have now seen a 3 phase socket that is only rated at 20amps (rather than the typical 32amp that I am used to seeing) and it looks the same size which confirms my theory.

2006年8月31日 · Firstly, if I have a 3 phase outlet (lets say 32 amps), a 12 x 2.4 dimmer pack and a selection of 240V fixtures that run on single phase. Some of the fixtures I want to run off dimmer channels (e.g. PARs), some I don't (e.g. intels).
5 wire, 3 pole, 40-50 amp - ControlBooth
2011年2月20日 · 40-50 amp, 3 pole, 5 wire, 120/208v, locking maybe ?. I need to either downsize the fuse panel to 30 amp, so as to use an L21-30 connector, or find this beast. Application is a dimmer PD (distributed dimming), with a demand load of potentially 25 amps per phase. I spec'd it as a 40 amp service but can lower that to 30 if needed.
Can someone explain 3-phase electricity? - ControlBooth
2006年3月8日 · When you see a three phase distro, this effectively takes three phase and splits it into several single phase outlets. Commonly, 3 to 4 10A single phase outlets will be branched off of each 32A three phase Active. Thus, you will see distro units with 9 or 12 single phase sockets on them and most will be marked as phase 1, phase 2 and phase 3 ...
3-phase distro and 2-phase service | ControlBooth
2023年5月19日 · The assumption of 520.53(B) is that when a road electrician with a 3-phase dimmer rack is presented with a split-phase service ( 2 hots and one neutral), they are going to connect their two most lightly loaded phases to L1, and their most heavily loaded phase to L2.
Getting power? 50 Amps? | Page 3 | ControlBooth
2007年6月11日 · 10, 15 and 20 amp sockets are physically smaller and also need an adaptor, and careful thought so you don't overload them. This is a 50 amp Clipsal outlet a la the type in question: I have worked a few Sydney venues where the 3 phase outlet is rated at 20amps, yet the male plug on the end...

2006年8月31日 · In 3 phase, you can't get a neutral current higher than the highest neutral current, because the phases are always 120 degrees out of phase. Say when phase A is at 0 volts, phase B will be at root 3 on 2 x 240 volts and phase C is negative that. When all equally drawn, the current balances out as A+B+C=0. With zero load on phase C. A+B
What load (in watts of lighting) can a 32amps industrial socket bear
2014年5月5日 · On each phase, you can run 7 1000w lamps if you are not running them continuously for more than 3 hours. If you are running them conitnuously, or are using 120v PAR64 lamps in series, then you can connect 6 per phase. If you truly have a 3 phase connection with neutral, this means you can run 18 or 21 lamps maximum from the outlet.
Control/Dimming - 208 volt on 2P&G? | Page 3 | ControlBooth
2012年11月5日 · 3-phase electricity requires all 3 phases to be called 3-phase power. Single phase power refers to a circuit with only one current path - either hot to neutral, or hot to hot. You can have 208 volt single-phase power in the sense that it's delivered via 2 legs from a 3-phase service, perhaps using an NEMA 6 or L6 receptacle.
Difference between HPL 750/115 and 120's | ControlBooth
2006年7月5日 · For any particular lamp, light output varies by a factor of 3.6 times and life varies inversely by a factor of 12 times any percentage variation in supply. For every 1% change in supply voltage light output will rise by 3.6% and lamp life will be reduced by 12%.
