For every 50 feet of cable/wire up to #8 upgrade next size, consult codes double and triple length runs.

Ex: #6 is sometimes mandatory for a 200 foot 12 amp run but can be used up to 300 feet on a 12 amp circuit.


Note:

Each time an additional plug is used in line of the run using 80% safe load, subtract an additional 2% from the over all power usage (80%to 78%).
Ex: One plug into the wall counts as your one 'free' plug.


WARNING: extension cords ARE included in total length from breaker box (+25 feet and one gauge up),
for continuous use at said MAX safe power usage.

Need make sure getting what actually equal to said gauge (if making own cord from something like SJO cable).
Some places go by size and not current.
A 12 gauge standard wire is actually the size of 10 gauge solid.
This is to make up for it not being a solid connector.
Bring something to compare wire size with what's printed/stamped on sheeting.
It should be one gauge bigger in size than what's on the sheeting.
Ex: If you have a 1000W light and are using a 12 amp circuit, you should use a 15amp #12 extension cord no longer than 25 feet.
This info isn't complete and probably doesn't apply to many, cuz if your thinking this big you should already have a general understanding of codes and loads.
#4 (approx 65-75A each) used for 100-115 amp service
#2 (approx 90A each) used for 125-150 amp service
#1/0 (approx 150A each) used for 200 amp service
#2/0 (approx 175A each) typically for industrial or vary long run with a large load. 300-350 amp service
#0/3 (approx 200A each) typically for industrial or vary long run with a large load. 400 amp service

Service cable is specifically designed for extra service lines andor extra long (In structure or over-head) runs.
1/0 Gauge I believe isthe only service cable (or cable) sold connected as x/3 (retail),
provides a path fore both hots, the neutral and ground.
