Electrical service conductors coming from the utility pole are often smaller than the service wires going into the main electric panel.
This is acceptable due to the fact the wires from the pole are "free to air" which means they can dissipate heat quickly.
Wires inside enclosed spaces such as conduit have little to no ventilation and need to be sized appropriately or excessive heat build up could result.

There are separate code tables for wires in conduit "not more than three current carrying conductors" 310.15(B)(16) and "in free air" 310.15(B)(17). 2017 NEC. For a given conductor size and rating, ampacity rating in free air is greater than in conduit or raceway. By comparison: #2 USE 115 amps in conduit, and 170 amps in free air. Makes sense too.

Good video.. just to clarify something that you said (pretty sure you meant the right thing, but may have said it backwards).. you said the larger wires "generate more heat being enclosed".. A better way to say it would be something like, "the enclosure will retain more heat, so the enclosed wires are required to be larger so they generate LESS heat, so the enclosure does not overheat."

doesn't code say 4 or more wires require derating to 80% and so on. doesn't that make it unneccessary to upsize this particular set of wires. although its never bad to size up but still not needed

@@JaRa911 I'm not sure.. you'd need to check the code.. I suspect that "free to air" wires from the poles have a completely different standard interior wires, and then once you get inside a conduit additional restrictions apply - at some degree of crowding you need to start derating the amount of current they're allowed to carry.. environment temperature is also a factor.

Neutral is simply the intended current return route for the proper circuit. Ground is a fail-safe return path. They both are at the same potential (or damn well should be - see ground loops).

The weatherhead is the piece at the top of the mast. Basically a hood to shield from the elements. The drip loop is the literal loop in the wire going from the spliced area into the weather head. Loop should be pointed down of course since gravity will draw the water to the bottom of the loop, away from the weather​head@texaswelder9957

Looks very sloppy there's not even the correct drip Loop. The drip Loop needs to be below the weatherhead and like I said there's not even a drip Loop. The purpose of a drip Loop is when it rains water will fall off on the bottom of the u-shape conductors. Also it looks like those wires are touching your metal gutter or at least they're very close? And as we know metal and electricity do not mix.

I know this guy is not saying he's an electrician but he's doing things that he absolutely should not be doing. For starters the gloves that he has on they are 6going to do anything to stop him from getting seriously hurt or killed when and if he touches the wrong thing but videos like this sadly make others believe that things like this 9safe and they will be protected from shock and or death. The type of gloves we use to handle live wires are nothing like what he has on and require testing to make sure the6are safe to continue to use they are also not the inexpensive gloves like he has on in terms of price. The hot gloves we use ate also pretty expensive but for good reason. Bottom line please do not touch the wires going into f Your home from the street and do not touch the wires in your home of you are not a licensed and certified electrician your life/safety and home and belongings all depend on you not messing with this so please don't.⚡👍✌

We had a storm last week and a tree landed on our service drop. The house still kept power. I was going to cut the tree up with a chainsaw after the insurance guy looked at everything. Then I noticed the support wire/ground/neutral was severed although the others were intact. I don't know much about electricity which made me not want to mess with it. I've called the power company.

Lazy cheap ultility companies do not have to follow the NEC so get away with murder. They would rather have your house burn down then them have the proper size fuse but overfuse. Have seen them only use 4/0 aluminum wire that for us is only good for 200 Amos but seen them feed 24 row houses with ever house having either central AC or 3 or 4 window air conditioning so wire gets hot during summer days.

If you are using conduit you can buy xhhw-2 #2 aluminum conducts as a single length and cut it to size. Be sure to leave yourself a 3-foot loop out of the Weatherhead/Service head and the conductor coming out to be used as a neutral make sure you tape it with white tape. If you are not using conduit then you can use SE #2 Aluminum Cable and you would need to twist the strands together to form the neutral.

Also the two wires, assuming that’s a new build would be 120 volts each carrying 100amps. Usually width of cable dictates amps. 100 1”, 150 1.25”, 200 1.5”. And as a side note if that cable is live then he should not be touching anything with gardening gloves. 10 amps will kill instantly 99% of the time. So if either cable has a slight tear or any imperfections then his entire body inside and out would burn and his heart would stop.

For 200A service, it's 2/0 copper or 4/0 aluminum. 100 amp uses 2 copper or 1/0 aluminum. Earth grounds on 200A are 4awg to water or ufer, and 6awg is all that's required for ground rods. A 100A service uses no. 6awg for all grounds.
