When you upgrade wiring, swap out an aging panel, or add new circuits, inspectors are not just glancing at the work and ...

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 ...

They often don’t notice the wiring behind their walls, but those hidden electrical faults quietly create real risk in thousands of homes every year. Identify overloaded circuits, aging wiring, and ...

The demand to increase energy efficiency in electrical products is driving the development of more accurate measurement instruments. Modern instruments now can quantify incremental gains made as ...

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 ...
