What does that mean?

Back to Electric Stuff Page 50 amp service. What is it, really? The main is all wired for 50 amp service. Notice the connectors on the white, black and red wires. I had just enough wire to reach inside the Breaker Box, had to go to the store and by some connection lugs and shrink tube, it worked out OK. If you go back and look at the image of the 30 amp service you'll see I had 4 space saver breakers. Now I have 6 for a total of 12 breakers. 2 are the 50 amp, double pole mains. They are in the second and third positions from the left. Look closely and you'll see that they are tied with a little silver bar. It's the way all 240 volt breakers are done. Also note that the jumper is gone. On shore power, the lower bus is now being fed by the red 6 gauge wire, 50 amps at 120 volts. The upper bus is fed by the black 6 gauge wire, 50 amps at 120 volts. This means 240 volts at 50 amps = 12,000 watts. Or could be calculated as 100 amps times 120 volts = 12,000 watts. Or 50 amps times 120 volts = 6000 watts times 2 = 12,000 watts. If I wanted to I could put in a double pole breaker and tap into 240 volts of power, it just wouldn't have 240 on GenSet. On generator power it is similar, except that each bus is being fed by 30 amps of 120 volts for a max available wattage of 7200 watts. In reality the GenSet breaker will pop before it hits a full 30 amps of load. NEXT
