Sep 4, 2015 · Feed to the barn is 3 conductor direct burial cable. Two of them look like 00 AWG, guessing, but the wire is a good solid 1/2 inch across. The 100A breaker terminal will fit, looks like, #4 at best. Is there is "reducing" type terminal that will allow me to tight fit the 00 AWG wire and then insert into the breaker?

Jun 28, 2023 · If you're downstream of a main disconnect, you do not get the same derate that the utility gets, meaning 3/0 copper or 250 kcmil aluminum. You'll need to check what wire sizes the disconnects and panels that you can actually acquire accept and …

Jan 25, 2019 · There is 00 AWG wire going to a 150A subpanel. The main panel's main breaker will adequately protect this feeder and subpanel, so it can be fed without a greaker.cc You would either use a panel that has thru lugs, or a "lug breaker" (search term: sub-feed lug block ) which fits where a breaker does, but is just lugs.

Jan 31, 2019 · But for general use a circuit protected by a 25-A breaker would be wired with 10 AWG copper wire. Follow the instructions for the load you have and use #10 copper wire. Any statement on this 25-A breaker or in an accompanying leaflet about using #14 wire, must actually be a warning that #14 is the minimum size wire under any circumstances. It ...

Oct 20, 2020 · In the US, you are allowed to breaker for the ampacity allowed on the wire (back to table 310.15(B)(16). So your #1 aluminum wire is allowed 100A, so you can breaker for 100A. In the People's Republic of Canada, the nanny state needs to protect you from voltage drop over 3.00%. However they base this on your actual loads not breaker trip.

Here's the problem. When you upsize for voltage drop, you also need to upsize the ground wire in proportion. Normally a #8Cu or #6Al wire would suffice, but you need to bump it. AWG is based on proportion. You bumped 3 AWG sizes for voltage drop, so you bump 3 AWG sizes for the ground. Done! #5Cu isn't made, so you need #4Cu bare.

Mar 10, 2021 · On the other hand, if you actually had a 50A draw (which is possible on a 60A panel - e.g., if you connect a big electric car charger) then you would need 4 AWG just to stay within 5% drop! One option is to use a decent size conduit - e.g., 1" - and 8 AWG wires.

Jul 12, 2020 · My understanding is all buried wire in conduit must be THWN-2. Per Southwire's spec sheet here the end of the first paragraph reads: All Sizes Rated Both THHN and either THWN (sizes 14, 12, and 10 AWG) or THWN-2 (sizes 8 AWG and larger). It is baffling me that there doesn't seem to be THWN-2 in 12 AWG.

Nov 2, 2014 · The wire size is irrelevant because the equipment is not listed for parallel conductors. Or to put it another way, parallel 1/0 conductors would not meet code in this case. Your answer implies that they would. The code has to be considered comprehensively, not in dribs and drabs. And the most restrictive provisions take precedence. –

Jun 26, 2016 · How does one properly solder a 10 AWG copper stranded wire with an 18 AWG copper stranded wire. There are plenty of tutorials on how to solder same gauge wire, but what is the recommended way to solder wires that are significantly different AWG?
