Understanding the branch-circuit requirements in Art. 210 is critical to completing Code-compliant installations. Article 100 defines a “branch circuit” as the ...

CATALOG DESCRIPTION: Fundamental concepts in electrical circuits; circuit analysis and network theorems; linearity and superposition; series/parallel combinations of R, L, and C circuits; sinusoidal ...

Article 210 provides GFCI requirements in 210.8 and AFCI requirements in 210.12. These requirements apply to 125V receptacles rated at 15A or 20A (circuits are 120V, but the receptacles are rated 125V ...

Printed circuit boards (PCBs) are the essential building blocks behind almost all modern electronic devices. These components ...

For electricity to flow, everything needs to be connected in a big ring. It’s called a circuit. For example, the lights in most houses and flats are part of a circuit controlled by the consumer unit, ...

Last, but not least, we like to look at the I/O (Input/Output) circuits during EMI circuit board reviews. As a port of entry for external currents, I/O circuits are particularly vulnerable to threats ...

If a circuit board includes analog circuits, we also like to focus on those for an EMC board review. Similar to voltage regulators (discussed in the previous posting), analog circuits can also cause ...

AutomationDirect announces the release of a new White Paper, “Basic Pneumatic Circuits”, which discusses common pneumatic circuits that can be used alone or as building blocks in larger pneumatics ...
