Suppose you have a 60A breaker supplying a branch circuit. What size conductors do you need for that circuit? One table in the NEC says No. 8; another says No. 4. Which one is right? What does the ...

RF instruments and wireless transceivers often feature an input for an external reference clock, such as the ubiquitous 10MHz reference input port found on RF instruments. Many of these same systems ...

SCHURTER expands its successful range of FMBC NEO 3-phase filters with a low leakage current series for applications where leakage currents are restricted to minimal allowable levels. SCHURTER has ...

A variety of circuit protection devices can be used to help protect LCD screens from damage caused by excessive current or voltage transients. Overcurrent protection may take the form of a fuse or a ...

Security and fire alarm systems are designed for operation within specified current and voltage ratings. If these ratings are exceeded due to short-circuit or voltage transients, components may ...

In Part 1, we looked at how to size a branch circuit and walked through a simple example. So if you’re sizing a feeder, why don’t you do it the same way? Except in cases where a feeder is also ...
