Amps/watts

I was curious the limitations for a string of lights. Not even sure what size wire is used for lights. Does c7 and c9 come in different AWG sizes? How about allowable wattage on those strings? Standard lamps not LED.
Thanks,

18 guage spt-1, c-9 or c-7, 740 watts or 7 amps
18 guage spt-2, 1200 watts or 10 amps
16 guage spt-2, 1500 watts or aprox. 13 amps
twisted 12 guage, 1725 watts or 15 amps.

bear in mind that even though a wire may handle amp load, your voltage may drop too low on the distance it requires to achieve that load. on 18 inch spacing and up this becomes an issue.

So 18" would be your limit on spacing? Can you order your lights with specific spacing or are there standard limits already in place,..6", 12", 18"...etc? What is the most widely used spacing?

What is the safest way to tie off while working on a roof?

What is the best method for lighting large trees? (ladder/lift)

Is holiday lighting something that 1 person can do or does it require more hands?

Thanks,

worx- Hotrod is right, I'd read some threads on here for a few hours and you'll find answers to most of those questions, plus it is a great education in the Christmas light biz. some answers I'm not sure you will find-

C-9s come in many different spacings, guages, and also different insulations on the wire. 12 in spacing is the most common.

There are several companies that sell safety harnesses for roofers, and they will tell you how to tie off and how to be safe.

I know here, MIOSHA does free training. So you might want to look into that.

Thanks fellas. I have read all weekend long. I have searched every word and phrase for information that I can think to search. Still trying to get my hands around some of this stuff. I realize I'm late for this year, but a little practice and I should be right on time for the next season. I would like to determine what my market will support as far as pricing goes.

I made the call to HBL and spoke with Mark today. I like what I heard and I am interested in where I can go with holiday lighting in this area.
