16 Simple Wire Size 70, Sub Panel Pictures - My plan is to bury conduit from my main residence panel to feed this new breaker panel in the garage. Searching into those alternatives and the preference to save cash given the fee of cable it looks like 1-1-1-3 ser aluminum cable ought to healthy my needs and should healthy in 2" agenda forty conduit. Ser isn't always allowed to be buried even in conduit.
The >x circuit discern is based on double-stuff breakers, that are high-priced and don't work anymore because most new circuits want gfci or afci, which take a full space. And that's how lots of human beings were given nailed: they assume "i'm able to assist 24 circuits out of this panel" best to run smack into the brand new gfci and afci requirements on nearly every circuit. Whoops!.
In view that you would then have 4 conductors inside the conduit (neutrals in split-section do not count number), your cutting-edge restriction for any conductor could be eighty of the 90 degree c ampacity. This is typically now not a trouble because you commonly should paintings off a lower diploma-c column.
The workshop will be likely 2-three 20 amp circuits and a 15 for the lighting. There will also be a 20 amp circuit committed to ventilation—the fan load is to date < 5 amps, simply don't need to limit it.
100a breakers are much more luxurious than 50as. In case you wanted to do this with two 50a breakers, there are methods to do that, however both contain units of cable. You can not parallel, in any respect, at these cord sizes.
Since the cord is bigger than 6 awg, you can purchase just one color of twine and use tape to mark them black, red, white and green. So fee both "by using the foot" and an appropraite spool. You may use several other types of insulation in a raceway, including thhn, xhhw, xhhw-2. Use is for direct burial and may be used with out a raceway besides wherein uncovered to harm so that you want to sleeve it in % or steel raceway above ground. The problem is whilst trying to affirm this i find a whole lot of arguments however no longer sufficient solid code reference as to whether or not ser cable may be buried in conduit (raceways?). Yup this isn't to code, cable must be rated for wet locations to be buried apparently.
