What kind of wires are required for connecting a 250w probe start metal halide ballast to the corresponding bulb? Would a heavy duty (15 amp) extension cord short circuit under the high voltage load during lamp startup?
Folks I appreciate the help but I wasn't asking for current (or electricity 101). I am well aware that 250w is no problem for most wires. Simple fact. The VOLTAGE is what I am concerned about. I.e., pulse start metal halide lamps start up at 4,000 volts, in other words, well over the dielectric constant of air at 1cm (or several for that matter). If you take apart a ballast, you will see that the wires connecting the components are rated at 600 volts and 10 amperes. Normal house wiring, afaik, is rated for 240 volts. The wire insulation is what counts for voltage, whereas the wire gauge, or thickness, is what matters with amperage.
I bought a prefabricated mogul base + 15' cord, but I would like to continue this discussion for future reference.
