The Bureau of Reclamation published this manual and many others for trades and crafts workers at their powerplants they are all available online at the following site http://www.usbr.gov/power/data/fist_pub.html

Enjoy and be Safe....

This reminds me of air assault operations in the Army. Ground the vehicle, gun, tank, etc., using a hook wired to a stake in the ground The stake, an aluminum tent stake, was often driven no more than a few inches into the dry dirt, thin 22 AWG or so commo wire was your lead, and a wood mop handle with a piece of metal on the end completed the grounding tool. Nothing bonded, unless duct taping bare wire to a corroded or painted surface counts as a bond...

The amount of static electricity generated by a helicopter is amazing. It's a miracle we all weren't killed, especially with fueled vehicles full of ammo involved too.

I saw more than one ground rod man get launched with a big flash on pick up or drop off. You could barely see anything in the swirling prop washed dust as the helicopter lowered the 8-ton cannon or 5-ton truck full of powder, primers, and shells. Then there would be illumination and you'd look to find the ground stick, see if it was still in one piece, see where the man landed, and try again.

I must have more lives than a cat. Knowing the Army, they probably still do it this way. I don't think they get many EE grads or licenced Electricians in the combat arms...

I was unable to open this?

Good Morning, im Bob from the Philippines I am interested in Personal Protective Grounding for Electric Power Facilities and Power Lines provided by the US Dept. of the Interior, Bureau of Reclamation. newsletter that I tried to download it. Unfortunately a message "File no longer exists" appears and thus the file is no longer available Where can I have that free downloads or any other sources

Sincerely Bob

This link comes up and says the file is no longer present. I would be very interested in reading this document. The document is "Personal Protective Grounding for Electric Power Facilities and Power Lines" from the US Department of the Interior.

I have been enjoying receiving your emails. I find the emails to be very helpful and a great source of information. I save or print just about every one of the documents, such as above, that is sent to me. This have helped numerous times in my business. I also find your NEC questions and answers helpful. Keep up the good work. I will continue to be a strong supporter and to spread the word about your website and tools. Thank you, Tony Perryman, PE

Mike,

Thanks for the link to the grounding reference. There are many many good documents on the Federal Govt web sites that have excellant information.

In particular the Military Facilities Engieering.

Tahnks again and God's Blessing to you.

Bud

Mike, the Bureau of Reclamation grounding paper is excellent and you are to congratulated on making it available.

With reference to helicopter static electric charge--all items in an air stream--cars, planes, etc. do this. Aircraft have trailing static discharge conductors to dissapate the charge, but when near ground like a heli, there is real risk. Wind blowing over an airliner sitting on the ramp will charge the window glass like the capacitor that it really is. The window washer will only forget once to ground the glass before washing it. And, of course, the whole craft sits on insulating tires. That's what all the ramp ground points are there for. What a big capacitor!

I have also learned that when an alleged deenergized circuit that runs in the same conduit or wireway as an active variable frequency drive circuit, the carrier frequency of the drive will put about a 30 volt and nasty tingle voltage on the deenergized circuit. Hence, a trip to the car for some cheap aliigator jumper wires from Radio Shack so that I can ground 1 end of the deenergized conductor.
