I'm no genius either, hopefully Ship or someone will post here, because there are people here that know ALOT more about this than I do, but I want to chip in because then they can tell me what I do wrong

Basically, there are several factors about electricity,

voltage, amperage and wattage. I cannot explain them very wel, but

voltage is how much energy is in each atom. Are you on 240? Amperage is how many atoms there are, and wattage is how much energy something pulls. (again, don't trust me on this, make sure that Ship or someone clarifies, I might have those wrong) they are all related by forumalas, but I do not know them. Like, if you know two things, ou can use a formula to figure out the third.

All things use

power, and you can see how much by their amperage and wattage. Standard circuits in the US are 15 amps, with special plugs for 20 amp, at 120 volt. Say youo have a

power saw that takes 15 amps, then you hev to have a 15 amp

outlet (which is what most outlest are) and a 15 amp cable. If your extension cable is only ablve to carry 13 amps (ther ewill be a

rating on the box of extension cords) then you shouldn't use it, it won't give enough

power to your saw. I have no idea how many amps

dimmer packs draw, it ought to be on there somewhere. Wattage is another thing that electrical things use. Most lamps here in the US are 300, 500, 575, or 1000 watts. On a

dimmer pacck they will say how many watts each

channel can handle, and how many the

dimmer pack can handle total. If you have a 1200 watter per

channel 2400

watt total

dimmer pack, then you can only have two channels fully loaded on at the same time. If you turn on a third

channel when the first two both have 1200 watts on them, and so does the third, then you will blow a

fuse or a

breaker. All your lamps will have a wattage on them. So, first youo need to make sure thep lacec youo are going to has the

power hookup you need, the right

voltage and amperage. Then, you need to calculate how many lights you are going to have, their wattage, and all that, to figure out how many ilghts per

channel, and how many will need to be on at the same time. For instance, in the pre-mentioned

dimmer with 1.2k

channel, 2.4k total, wattage, you could have each

channel loaded to 1200 watts (by using two 575

watt lamps) but, you can only have two channels on at the same time. Other

dimmer packs will let you have all channels on at the same time, say, a 4

channel pack, 1.2k/

channel, 4.8/total

dimmer pack,you could have all channels loaded to 1.2k watts, and all of them on at the same time.

Anyways, I have to go eat dinner, hopefully someone else can add to this!
