Every year we read about electricians, engineers, and supervisors who were seriously burned or killed while working in or near a circuit breaker (CB) compartment. I’ve personally investigated ...

THE Electrical Research Association has recently reported an interesting development which has taken place in connexion with its programme of research on gas blast circuit breakers. Normally the ...

If you’ve never used a voltmeter to test electrical circuits on 12-volt farm equipment, cars or trucks, but wanted to learn, here’s how: Voltmeters cost from $15 to $300. $50 will buy an economy-grade ...

Electricity is a powerful force that can cause serious injury and death. When it comes to electrical job tasks, it only takes an instant to turn a momentary mistake into a life-altering event or even ...

Here's what to look for, and how to fix what you find. Working on your own home is empowering, and it saves you money. Even before I became an electrician, I tackled DIY projects from plumbing to ...

We have all had difficulty testing diodes in-circuit. Most DMM’s have a diode Vf function that measures forward drop, but what is the normal voltage drop? Analog VOM’s attempt to measure resistance of ...

AN estimated 58 people lose their life each week as a result of electric shock. In an electrical system, the grounding system is the primary protection against electrical shock hazards. It provides a ...

Electricity is like the genie in a bottle. When it is contained and properly harnessed, its power is endless. However, when it escapes in an uncontrolled manner, electricity has the potential to cause ...

Final electrical test remains one of the best ways to assess a circuit’s ultimate viability. But we know that, unfortunately, even 100% end-of-line electrical testing of semiconductor wafers will not ...
