Mark didn't remove the neutral. He isolated the neutral from the grounding system so the live neutral wouldn't energize the grounding system. #1 Most people assume a ground wiring system is always at true earth potential which is false. #2 Most people assume that the ground system is capable of bringing a neutral conductor's voltage down to true earth potential,false again. No remote sub panel(s) away from the either the 1st electrical panel should have the ground and neutral bonded. If there is central metering in the middle of the yard with more than one building/panel being supplied. The only neutral to ground bond should be at the meter/pole. All the distribution panels should not have the neutral and ground bonded. Of course having a sound and functional ground system at each building service is vital. Bad enough some old corroded #10 bare wire and a rusty 6ft long ground rod into frozen sand. Two 10ft ground rods at least 10ft apart joined with #6 copper is absolute minimum. Still a hazardous situation when some jackleg electrician connects a standby generator neutral to the ground on a welder receptacle. Also bad news if the same tinkerer needs 120V on a machine with only two live lines and a ground. The intrepid tinkerer incorrectly wires the 120V load's neutral to ground and one live line. The tinkerer doesn't realize he has just energized the grounding system above true earth potential. Even with a good ground system let alone the typical ground system found in the real world. Putting neutral current on the ground system makes the grounding system hot. They do insulate that neutral wire with white insulation for a reason you know.

Today's Featured Article - The Nuts and Bolts of Fasteners - Part 2 - by Curtis Von Fange. In our previous article we discussed capscrews, bolts, and nuts along with their relative hardness and thread sizes. In this segment we will finish up on our fasteners and then work with ways to keep them from loosening up in the field. Capscrews, bolts and nuts are not the only means of holding two parts together. When dealing with thinner metals like sheet tin, a long bolt and
