Temp Power

Temp Power-2

1. tensile on the rod is 80,000

2. density is 1035 cold roll steel

3. diameter is 0.677

4. cm is 1.9

Hope this might help with the math calculation. i found the calculation on google but who can understand it? lol

Quote "what i would like to do is use a 3/4 inch ground rod cut in 8 inch lengths to attatch to the single open lug and then attatch a 4 hole lug to the other end to give me 3 open holes per phase"

That has to be the gosh most awful, worst, most terrible, not to code any where, unsafe, ugliest, contraption ever proposed in electric history. Why not use something that is approved and tested.

Hello, i thought there would be one person to leave a comment like you did. this is a temp solution to a problem i have. there is no room in this ATS to do anything else. this is a live data center. the math calcs out to over 613 amps at 80%. by the way befor you put me down like you just did, go look at STORM COPPER COMPONENTS round rod. there 3/4 inch C11000 round rod is rated at 1300 amps and can be used in this application. again this is a temp solution, and i was just asking for the calculation to see if this MIGHT work. instead of posting such nasty comment why dont you give me your idea on how to do this in an ATS that has zero room in it, only one open lug to put 3-4/0 cables in,factory fixed lugs (no bolts to conect to)??????????????????

thank you

PS. This ATS can not be shut down. power loss = 1,000,000.00 a minute yes that is ONE MILLION DOLLARS A MINUTE

AMP makes a paddle that should do you quite nicely and they are rated and UL/IEEE approved!!

Thank you, i will look into that.

Don't forget, Temp power has the same potential for catastrophy as Permanent power, maybe more.

Ground rod is not designed to carry current. DON'T use it.

If you need to conect a lug pad somewhere else, look into using Flexibar, made by Erico. They have 1200A available.

This is a good answer. Remember that the length of the conductor is important. A buss outside the generator would also help as the code still has a tap rule and it does work.

I was just kidding you with my comments. But I want to stress, just as JR did, that this installation must be done correctly and to the code. I need to ask questions.

Quote " have a 1200 amp ATS that will need to be worked on. my delima is the generator feeds are trip 3 inch conduits with 3 600mcm in each. i am going to run temp cables to bypass the generator conduits so i can install a 1200 amp board in the run. Why a 1200 amp? Get the max demand for the building from the utility. It is probably much less that 1200 amps. Are you having to provide temp power to the entire building?

i have spare lugs open at the generator so this is no problem. here is where it gets tricky. What is the max amp output from the generator?

at the ATS on the sixth floor i have only one lug open for 3-4/0 welding cables to land. what i would like to do is use a 3/4 inch ground rod cut in 8 inch lengths to attatch to the single open lug and then attatch a 4 hole lug to the other end to give me 3 open holes per phase (fallow me so far?) What is the max amp load at this point? Why do you need that many cables? Is it for welding? Very confusing?

what i need to know is what the amperage rating is for this 3/4 inch rod?, the total load on the ATS is around 400 amps at the peak of day. this will be in place for approx 2 weeks. as you can tell by my typing skill im not that hot in math either. Are you attempting to install the rods for welding circuits. Your project is very confusing. From the way it sounds you have no OC protection for these ckts.
