Theses lights were made for commercial use in suspended ceilings! Need to know how to wire them to be used for 220 volt usage!
Quadra mark is commercial metal halide light
It appears the 208-240 480V model is different from 120, 277 or 347V model.
You cannot connect 277Volt light to 240Volt
These are two different things.
Commercial 277V has 1 hot leg and a neutral (very similar to residential 120V which also has 1 hot leg and neutral)

While residential 240V has 2 hot legs
http://waterheatertimer.org/See-inside-main-breaker-box.html
Check rating label on light and see if it shows 120V in addition to 277V
If rating plate shows 120V, then it should work.
Residential 240Volt has 2 hot legs, each Hot leg measures 120V to ground
So you can use one Hot leg from the 240Volt breaker, and use ground wire to make 120Volt circuit.
Using ground wire to complete circuit in this manner is completely out of code and not recommended by any professional electrician. But it will work.

Thank you! On the Splice Box Cover it is marked with the Model & 277 Volts 1.75 Amps! Inside the Splice Box is a White Wire coming from ballast connected to White wire from Igniter & the Lamp!There is also a Red wire coming from Ballast & Igniter with a Black attached wire marked 120 volt & A Black wire that comes from the Igniter that is connected to a white wire attached to a inline fuse with a Red wire with the end stripped & A Green service ground wire! I want to use these in my garage as lighting & have no preference whether they need to be hooked up using 110 or 220! The Black, Red & green service ground wires are all stripped on the end from factory! Are both the Black wire marked 120 volt & the red wire attached to the fuse to be connected to a hot leg from the breaker?
Guess is needed. I could not find wiring diagram for light. You could also take the light to local electric supply company, or local electric repair company. 120Volt has Hot-black and Neutral-white and Ground-bare copper. Connect 120V Black to lead marked 120V. Look for a separate white wire, and connect 120Volt white. Do not connect the red wire at this time. Again this is a guess. Attach photo.
King of new to the site & not sure how to attach photo! I looked again & did find a White wire with a sticky attached paper label! It appears as trhough this white wire & the black wire marked 120 volt lead to the lamp! would it be safe to just try & wire a plug using the black as hot & the white as neutral & plugging it into a 110 outlet? I don't want to hook it up wrong & smoke the ballast
Not sure how you attach phot either, and I've been at this site for years. Some folks attach photos however. BUT... in this case, I'm not sure a photo is needed since you describe the wiring so well. By code, both 277V and 120V require a white neutral wire. I suspect the white wire is white neutral for either voltage, and then the black with 120V label is the Hot 120. Use a multimeter and see if there is ohm reading between the black and white wire.http://waterheatertimer.org/images/multi... The next step would be to connect the wires, or safer yet, drop by electric retailer and ask them their opinion. Or contact Cooper except they may not respond other than to say contact qualified electrician in area ... which is why I suggest stopping by electric supply house.

SOURCE: I want to put a on and off switch just like a
On the compressor or in the manual it should say the Full Load Current or Full Line Current (FLC). I would go by that to size your switch.
They make motor rated toggle switches which look the same as a light switch. You would need a *blank* amp motor rated 2 pole toggle switch it should have 2 screws on each side excluding the ground. The left side screws should have one circuit on them and the right side should have the other circuit on them. Mount this in a metal box with a "RS switch cover" for inside installs or a "Bell" or ferrous box for outside with a weatherproof switch cover. Make sure you buy a big enough box to fit the switch and room to bend the wires. Also are you planning on just cutting a cord and running to the switch or hard wiring? Make sure to get appropriate connectors and if it is exposed to possible damage consider using flexible mettalic conduit.
FYI in most cases a switch can not be oversized it can be undersized however.
Feel free to write back if this is unclear.
SOURCE: how to wire 4 prawn 250 volt plug
The 2 wires coming off the double breaker should go to the x & y of the plug. The ground should go to ground (green or bare) and the other prawn left over is the neutral wire, it goes to the buss bar in the breaker box with the grounds ( usually with a bunch of white wires )
SOURCE: need to know wiring diagram for cooper single pole lighted switch
well lets see on one side you should have two brass screws that would be to interupt your lead to the fixture then you either have a brass and silver screws on the other side or you have black and white wires the black or brass is always hot the silver or white is neutral does that answer your question if not hit me back with a description of what your switch looks like
SOURCE: What size amp switch do I need.
first of all, i am not sure if you are knowledgable on electric circuits....your breaker panel is probably a single phase which is nominal so your compressor being a 40 amp 220 volt unit needs a dual breaker at 40 amps meaning that both the black and white wires go to the breaker......then if you want to also add another on-off switch in line with it to control it from another location, you can use a single pole, single throw switch rated for at least 220 volt with contacts that can handle at least 40 amps or higher.....you would connect such a switch by cutting either the black wire and connect both ends of the cut black wire to the 2 contacts of the switch or you can also do the same with the white wire......by using a single pole switch though, one side of the line will always be live even though you shut off the power......you can use a double pole, single throw switch to connect both the white and black wires to, which will completely cut off the power when switched off....if all of this is too much to understand, then just use your existing 40 amp breaker in the panel as your on and off switch........good luck....be careful as 40 amps and 220 volt is extremely LETHAL........good luck

More information is needed.
Is the circuit breaker 240Volts or 120V?
Is the pump 240V?
What kind of switching timer is connected to pump?
What color are your wires?
Read information below and then add a comment.
Typically, the pump is 240Volts.
Pump is wired to mechanical timer with NO NC contacts for example GM40 series:
http://www.intermatic.com/products/ec%204%20layer/mechanical%20time%20switches/24%20hour%207%20day/gm40%20series%20multi-voltage%20time%20switch.aspx
http://waterheatertimer.org/Intermatic-timers-and-manuals.html#GM
The timer sends power to one speed or the other speed but not both speeds at same time.
Timer can be mechanical or digital.
Mechanical timer is used if pump is supposed to be ON at all times.
Digital timer like P1353 is used to control pump more exactly.
http://waterheatertimer.org/Intermatic-trippers-and-parts.html#P1353
See example1 for 240V
http://waterheatertimer.org/images/P1353ME-2-speed-motor-500.jpg
Timer is rated or set for 240Volts.
GFCI protected 240Volt line leaves circuit breaker and goes to timer. Then timer and pump are both protected.
