Very good help - well done in all the concepts covered in what might be = perhaps a FAQ in the making on such a thing. Doubt in re-plugging switching hot for
neutral would reverse the motor as not posted.
Still in any such post I would start with brand and type of
mirror ball motor, size of
mirror ball run, and
dimmer type controlled off of in that some need a
relay, others can be fine in
switch mode. This just as some are fine with dimming if not
DMX controlled for speed which is its own ball of wax.
After that... Adaptors, Adaptors, Adaptors. Your initial question was in asking about someone else re-wiring your gear and questioning potentially him doing so. If this is going to be a frequent thing, this borrowing of your gear, and or something you might reasonably expect such as converting
stage to
Edison than you should have say 18" adaptors pre-wired for such a purpose.
Rule of thumb on making adaptors is never jump to more than one amperage
rating: if using a 15A
plug and 20A is available you cannot jump to 30A. This as with requirements of single
conductor feeding into multi-conductor plugs not allowed without special work, and overall say you cannot feed even a 60A female from a 400A service if that 400A service is not fused or breakered down by way of the service panel or your
adaptor including
circuit protection to
cover for maximum rated amperage of the
adaptor. Also
voltage concerns = even if your say moving light is auto sensing for
voltage, really bad Karma to make a even 15A 250V
adaptor to 15A 125V
adaptor. Such a thing should never exist due to the likely possibility for someone to
plug something not auto sensing or switched in
voltage into 208V
power. Instead if really necessary to go 208V to 125V and while pain in the rear most often heard, it is more safe to say go 208V to
stage pin that's dual
voltage rated and attach that
adaptor as needed to a
stage to
Edison or in general 125V
adaptor. Yes, can still blow up a few zenior diodes in the
fixture - this if not
circuit board in going one way or another in doing so but by way of what adaptors you provide it was not by way of you in doing something that is not a good thing to exist.
General rules, 18"
adaptor is most useful and only one step up or down in amperage - normally within five amps and after that
fuse or
breaker protection between larger amperage
power supply and
outlet or ok if larger
connector as long as fused or breakered to assure it's going to trip before cable or
plug fails. No jumps between voltages unless those plugs adapted to are rated for dual
voltage.
Further thoughts, if making say a three
phase to single or dual
phase adaptor, marking which phases are tapped is very important in noting on the
adaptor so as to balance the load or not to draw too much off any one
phase.
