Hello. As far as I know, every circuit capable to flow current must be closed. In other word, open circuit can not flow the current, obviously. Right now, I would like to know this is also true for lighting in bad weather. When bottom of the dark and heavy cloud get more and more...
live and earth, the light fitting should a so be live earth and neutral LED polarity is sensitive ie it dont work the wrong way around perhaps just swapping the supposed live and neutral around and the pull switch on may do the trick but make sure the circuit is dead at the fuse box ...
1) (US) No Color (US equivalent of UK's OPEN WHITE).2) Not Connected (in a circuit diagram). NON DIMSChannels, usually controlled from the lighting desk, which are switched, rather than dimmed. This enables motors, slide projectors, smoke machines etc to be controlled from the lighting ...

It must be checked that all fuses and single-pole circuit-breakers and switches are in the ‘line’ side, that the wiring of plugs and socket outlets is correct, and that the outer contacts of concentric bayonet and screw lampholders are in the neutral (or earth) side. 38.15.2.5 Earth-...

In the diagram above, the fused rating of the power supply must not be exceeded, so more than one power circuit should be used for the moving lights and LED Pars. Some low-wattage fixtures have the ability to connect a power output to an adjacent fixture, so that the need for ...
Basically, I added anew outletto that existing circuit using ahandy boxmounted to a stone wall. Of course, I do have some notes with this and maybe there’s a tutorial to come on it, one day. For now, though, all you need to know is that because my power pack was inside the mech...

you perform what is called a continuity test. This is where the firing system checks each cue with a very small current, not enough to ignite them but enough to check there is a complete circuit. If any cue fails then you will need to check the connections, your wiring and possibly try...
