| | | Falling off a lift is often a fatal error. But it’s not the only way in which electricians die when making mistakes in how they use a lift. Electrocutions also happen. For example, raising the platform without watching where it’s going can mean driving your shoulder or head into an energized, exposed conductor, such as an open bus connection. |

| | | Despite plenty of EC&M resources on grounding and bonding, including theory and specific rules on the topic, the simple question we continually get from electrical professionals in the field is: “So how do I have to ground and bond?” The National Electrical Code (NEC) lists eight specific methods to make grounding and bonding connections in Sec. 25... |

This is definitely what I consider a cross-code (or cross-over code) issue. Not only do electricians and builders not know the proper installat... |

| | | Arc flash reduction methods must be considered before working on energized electrical equipment for personnel safety. The idea behind energy reduction is to place energized electrical equipment in a state where less arc energy is available when an arcing fault occurs. These techniques range from the obvious (de-energize!) to more complex and costly... |
