Electrical snafus are among the most annoying problems with older cars. Unlike tires or bodywork, there's something about electrical systems that seems to baffle many car crafters. We could blame it ...

The NEC provides a recommendation on voltage drop for branch circuits in Informational Note No. 4 following 210.19(A). A similar recommendation for feeders exists in Informational Note No. 2 following ...

Let's start with DC voltage, one of the simplest and most-used multimeter measurements. The DC voltage measurement is used to determine the difference in electrical potential between two points in a ...

For over a decade, thousands of users have deployed permanent electrical safety devices (PESDs) to reduce the risks in isolating electrical energy. This elegantly simple innovation increases the ...

What type of equipment is best to use for low-voltage test of battery cells? What is an electronic load, and how does it work? How to overcome a major limitation with the low-voltage-discharge test.
