As said earlier this a motor starter question. We need the name plate of each motor, then we can tell you which starter to get.

I'm an EE and this is correct. Here is how it its done: I usually size breakers between 175%-200% of the Full load current for the motors. I almost never specify instantaneous trip breakers these days. Fuses (Dual element time delay type) is 175% max. This is all in table 430.52 of the NEC...

Not sure how big the holes you are drilling are but I have had great luck with diamond coated hole saw drill bits. I usually drill the sides of fish tanks for bulkheads. The best method I found is to use a small puddle of water to keep the bit cool and just let the bit do all the work. Do not...

There are many different 240V receptacle types(based on NEMA configuration). You should verify which type you have for your dryer and go from there. The welder should tell you if it has a neutral or ground or both. It will be obvious at the point if the outlet you are referring to will work or...

75 degree #1Cu is good for 130A and #1/0 Al is good for 120A according to the NEC 310-15. My guess is they have a general rule of thumb to use ** size cable for ** amount of distance at 100A. I would challenge the inspector as to where in the code it says that or what code he is referring too...

They actually make 90 Degree terminations now. I have specified them on a few jobs I have done where I had an existing conduit I needed to utilize. Obviously its very rare so you are correct in saying we should be using the 75 degree column.

It would need to be a 90A breaker since it is not a dwelling unit service entrance conductor.

Article 310.15(B)(7) is what you are referring to. The table in that article allows a bit more amperage on service entrance feeders for dwelling units only. It makes sense because most residential applications have large demand factors and very little continuous load.

What is the load on the panel?

These are must haves if you ever do any work on VW/Audis. Well worth the price in my opinion. I have the same set and use them pretty often. They are very durable.

is this guy serious? $9500? No way! http://newyork.craigslist.org/fct/tls/5204729328.html

The first picture was when I was moving stuff from my old box to this one(kind of messy). My application may be different from many folks on here as I really only work on Audis/VWs. I use my tools more than the average home mechanic since I do rather big jobs. It works for me so far but like I...

I have the 9 drawer 52" husky cabinet. I like it for the most part. Logistically it was just easier for me to borrow a friends pickup and bring it home than dealing with having it shipped. I do agree that the 11 drawer is probably a bit better. One thing I would recommend to anyone buying one of...

I have a mix of sunex, HF and GW 1/2" impact socket sockets. My 1/2" deep impacts are all HF except for my 18mm which is mac lol. The GW sockets are great and excellent quality. i have had them for over a year and never had an issue. The HFs i have had for 2 years and they are durable but are...

So those 2 breakers are you main disconnect where you would have your grounding electrode (ground rods) bonded to the neutral. Kind of odd that its not right near the panel. I don't think i have ever seen a 55amp breaker before. But maybe its some old school junk before my time. In any case, the...
