It is absolutely not within your bounds to be doing this without trained supervision. Sorry to say this and even in asking here, there is stuff that cannot be adiquately explained or shown on the net and without eyes on the topic. Such things as proper
strain relief, ferrules and what
wire goes where are easy to explain but without following the instructions and having a torque screw
driver on
hand, how does one go about telling but not verifying 1/4 turn past finger tight with words?
This wiring of a
stage pin connector as from what I read I would guess is very easy but there are ever so many little details.
Given it's a
stage pin/slip/2P&G
connector as described than there is also normally letters printed within the
plug. At very least that center pin which sticks out further than the other two will have a "G" next to it. G for
ground and green.
The other two in this specific
instrument don't really matter unless the wires are coated in a specirfic color. In actuality, it's a dual pin lamp thus it does not matter which color or
wire goes to which pin because both serve the same purpose. In a screw
base or medium
pre-focus, even some special
bi-pin lamps where the pins are of differing sizes it will matter but hot and
neutral on a
ETC fixture are interchangable given the lamp
base and lamp.
Pick one
wire and make it hot - the one furthest away and normally black as a color, and the other as
neutral/
return or white in most instances. For Euro it's brown and blue much less there is other colors in use all around. In the US, the only colors sutible for
ground are green or green and yellow or white with a green stripe. The only colors for
neutral are white or grey and if on a Euro
fixture blue as opposed to brown. Otherwise the primary "hot" colors are black, than red, than blue, and orange with caution as to if it's a high
leg or not which is bad to be tapping. After that any color of
wire is also hot.
This is as opposed to electronics and DC wiring where if I remember black is than either positive or
neutral.
As you can see in these small details, there is lots to the which
wire goes where much less what does what.
Now given even a maintinence person that knows hot
neutral and
ground you can if needed get adiquate supervision to some extent. Get a new
stage pin plug, pull out the directions on stuff like the use of
strain relief and
ferrule and have them verify your work for at least the first couple of plugs. They than are also responsible in supervision as necessary no doubt by the school board. Otherwise your instructor had at best get some training fast given this is what they are in charged of.
Any
book on
stage lighting much less electricity will also supplement this. But again, nothing replaces the need for supervision that there is not a mistake, things are done right and there is enough tension but not overkill on the screw
terminal. Much less that a
ferrule is used. We would about get into the size of a
ETC fixture's
wire in being 16ga. not
fitting too well within a normal 12ga
ferrule without some folding or a sub-ferrule. Details for later given proper tension that needs to at start to be verified. Plus the proper
strain relief used.
The instructions that come with new plugs are actually a useful and helpful read also. Even if a used
plug, buying a new one just for the instructions is well worth the say lunch money.
By the way there is other things to check on the used
plug such as gap
spacing and oxidation/arcing.
