The transformation of the power landscape involves more than just generation. The distribution of electricity is being changed as well, with technology designed to make electrical systems safer, more ...

The control circuit in Figure 1a allows you to manually adjust the power delivered to a load. By changing the setting of potentiometer R 3, you change the phase angle at which the thyristor (Q 3) ...

Circuits that fall under the requirements of Art. 725 are remote-control, signaling, and power-limited circuits that aren’t an integral part of a device or appliance. Article 725 includes circuits for ...

A new type of device provides designers of automated installations for North America with performance, cost, and safety benefits. Industrial machinery and equipment system designs typically rely on ...

How does the NEC control your signaling and control wiring requirements? Today's industrial facilities use a host of control circuits for motor control, instrumentation signals, and plant shutdown ...

This SCR phase control works much like the common TRIAC dimmer, but has numerous advantages including increased current capability, robustness and absence of minimum voltage “snap-on.” A complementary ...

Short circuit current ratings should not be overlooked during panel design. Negative impacts can occur to production, equipment and, worst case, plant personnel. Per 2014 NEC Article 100, short ...
