It’s not unusual that solar photovoltaic (PV) systems would require fuses – after all, these installations can carry substantial electrical loads, so overcurrent protection is critical to their safe operation. What is remarkable, though, are the conditions under which PV panels, their conductors, and their wiring can operate.

Recently, my wife and I spent about two months down in Little Rock, Arkansas for medical reasons. We rented an Airbnb property, a four bedroom house with two baths. It’s more than we need, but considering our daughter and son-in-law were going to bring our granddaughters down for visits during school breaks… it was really just right.

Keeping hospital balance sheets profitable is a challenging proposition for healthcare organizations. That’s certainly one reason why so many have undertaken lighting upgrades over the last decade to move to more efficient LED lamps and fixtures.

In the constantly changing world of lighting technology, wireless fixture control marks a significant leap forward. These systems, defined by their ability to manipulate lighting conditions, without the need for hard-wiring, are swiftly becoming a vital tool for electrical contractors and lighting designers.

Uncle Bob and Aunt Betty's two-story farmhouse was a haven for my brother and me during our childhood. While it didn't boast modern amenities, the old-fashioned radiators under each window ensured a cozy warmth throughout the house. These radiators were a blessing during cold winters, providing a spot to dry our snow-soaked gloves.

The concept of 3D printing, also known as additive manufacturing, initially surfaced in the 1980s, thanks largely to the innovative work of engineer Chuck Hull. Hull invented a process called 'stereolithography', or SLA, a method that allowed for the creation of 3D models layer by layer, literally bringing ideas to life. It was a revolutionary breakthrough that sparked the beginning of the 3D printing era.
