Okay so as a starting point lets say I know absolutely nothing about electricity, fuse boxs, amps, and safety knowledge. I was just going to pay an electrician to come over and give everythhing a once over and install anything i might need, like a dedicated fuse box and power directly for the basement(if thats even a thing).....Okay so how do I figure how how much stuff I can plug in safely without blowing a fuse? What do you do if you need more outlets or mor power to an area like my basement. Is it something an electrician has to install?? Any help would be great, Im also googling stuff but figured one of yous guys would be pretty savvy with this stuff........
you'd need a sub-panel runnin from the main box... which you can do... you can even run the line... then, based off what you said, get someone else to do that last hookup to the live power...
now, the issue here is wiring... when wiring exceeds its load, it heats up... obvious problem...
standard household uses 2 sizes primarily
15a @120v = 14 ga wire
20a @120v = 12 ga wire
Your wattage is your volts multiplied by your amperage...
the usable wattage at 20 amps and 120 volts is 2400 watts.
At 240 volts and 20 amps it is 4800 watts.
(its good to stay around 80% of your MAX... best not to push it... if you care about things like fire, that is...)
This is because of the amperage, which is a very specific number electrons passing through the wire per second. That electron movement creates the friction that heats the wire up if you get too many electrons flowing.
Voltage is the pressure the electrons are under....
the combination of volts x amps = the net FORCE.... or watts.
Exceptions are made with regard to the length of copper wire..
once you get over a few hundred feet the wire carries less wattage because friction in the wire causes the voltage to drop.
If you call a guy, I'll give you advice someone once gave me....
Ask for a 50 amp sub panel.
Tell them you want a 240v outlet for a small welder at 30 amps.
And then ask for a couple 120v 20 amp circuits.
30 amp @240 will run 5 1000w lights safely, with a little extra for safety. (MAX of 7200w... but using -80%)
20 amp @120 will run a small A/C and exhaust and circulation fans.
If you need more lights... imagine a bigger welder... and ask for a 50@ or even 60a @240
