Give proper attention to solar wire management

Solar mounting systems are typically designed with one thing in mind: Get installers on and off the roof as fast as possible. One thing commonly overlooked by racking manufacturers is wire management. By integrating wire management into the solar racking system, not only are wires and cables protected from damage throughout the life of the

The PV junction box: An overlooked, yet important part of a solar panel

The junction box is often an overlooked piece of the solar panel. Usually pre-installed on the backside of a solar module, installers pay it little mind until connecting panels. The PV junction box has a simple, but important role: housing all the electric bits on a solar panel and protecting them from the environment. Wires

Follow the rules when installing solar AC cabling

ACPV systems use microinverters, which fully convert DC power to grid-compliant AC power at each PV module. One of the benefits of an ACPV system is that there is no high-voltage DC present. This reduces the need for code considerations and product functionality related to compliance with safety requirements for high-voltage DC circuits. It also

Install the wire box before the string inverter

Contractors can install string inverters with integrated, but separable, wire boxes more efficiently by installing the wire box first and then focusing on the inverters. Employing the appropriate skilled workers to align all wire boxes is essential to quickly complete DC and AC wire termination and connection. Once the wire boxes are in, less-skilled, lower-cost

Avoid mis-wiring an east-west array

As east-west arrays become increasingly common, they bring an important additional requirement: The modules on the east and west orientations need to be wired to different inverter MPP zones, or different inverters entirely. This can slow down electrical installation and, more importantly, create opportunities for installation mistakes. These mistakes—specifically, when east- and west-facing modules are

HellermannTyton’s new mounting option suspends cable and wires via sling strap

HellermannTyton announces the Dual Arrowhead Sling Strap, an eight-inch nylon strap resembling a cable tie with arrowhead fasteners on each end designed for insertion into dual quarter-inch holes in the work surface. The result is a loop that securely hangs cable, wire and conduit without a binding force. “This product was originally developed as a

General Cable awarded for innovative heat-dissipating technology

General Cable Corporation has been named a 2017 Award Finalist by the internationally Edison Awards for its TransPowr overhead conductor with E3X technology. The awards–inspired by Thomas Edison’s persistence and inventiveness–recognize innovation, creativity and ingenuity in the global economy. “This award is a recognition that positions General Cable as an industry leader and forward thinker,”

HellermannTyton offers heavy-duty adhesive cable mounts

HellermannTyton offers a new line of extreme-duty adhesive mounts designed to attach cable and wire bundles with extraordinary adhesion even on difficult surfaces. The mounts accept most cable ties, and are made of a proprietary PA66 blend to resist impact, heat and UV exposure. “During our field research in heavy equipment and auto manufacturing facilities,

Multi-Contact now known as Stäubli Electrical Connectors

Upcoming 2017 changes for solar labeling

This article is reposted with permission from Graphic Products. See the original blog here.  When solar labeling first surfaced around 1980, there were no set standards. Over time, the National Electrical Code (NEC) included solar systems and labeling in its standard, which started with the 1984 edition, with the most current revision being the 2017
