Fun, oh' yes. Beyond straight blade "
Edison styles" that in the 120v/20a version will thoroughly confuse
stage hands into installing new 15a versions of the
plug on the cable so they will fit into the 20a outlets. To
twistlock, to
stage pin. Adaptors abound everywhere in our industry - especially
twist lock type
adaptor. Depends upon when the place was built. Even have two or three places that use a
twist lock alternative that's non-NEMA in having a fourth style beyond just 15 and 20a versions of the twist plugs without a standard.
Plus there is 120/208v switchable moving lights that require either adaptors that are against good practice in converting between the two voltages or the various adaptors to a set of dual
voltage stage pin plugs taped in between to make it work say from 20a twist/208v to
Edison.
Than now we are getting into the Euro pin and sleeve
plug such as the Cee Form 16a version. Darned
Led cyc lights that now need adaptors to the above stuff in addition to. Much less the Kenisis
hoist system using 5-pin Cee Form instead of 5-pin twist I already have, I'm building even more cable for next week. This as opposed to just more adaptors.
The CEE Form type of pin and sleeve style of
plug itself has differing
voltage and style ratings as I found out later in having to re-install the plugs on some adaptors after having found out later hey were not the same.
Than there is even equipment using the ML series if not the Speakon/Powercon type of
plug, or even 3-pin
XLR plugs for a
power/data signal.
Lots and lots of adaptors abound here.
