In 2023, the committees of the National Fire Protection Association (NFPA) published their most recent updates to the NFPA 70, better known as the National Electrical Code or NEC. Updated every three years, the NEC is the benchmark for safe electrical design, installation, and inspection to protect people and property from electrical hazards. New requirements specifically relating to surge protection emerged in both the 2020 and 2023 NEC iterations. And while NEC adoption by state varies, the consequences of failing to comply with NEC codes can be costly, endangering both people and property and resulting in expensive fees/repairs. Therefore, it [...]

Integrators and end users love Power over Ethernet (PoE) devices for their cost and time saving benefits as well as their ease of use. By delivering power and data over the same Ethernet cable, PoE devices can easily be connected, disconnected, and moved without the need for extensive cabling or electrical work. From IP cameras to access control systems and beyond, PoE is now the go-to solution for locations where power outlets or network connections are hard to come by. The low-voltage install of PoE devices is further simplified by PoE switches, which provide power to peripheral devices via a [...]

For proper operation, install all Surge Protective Devices (SPDs) per the guidelines set forth by the manufacturer. Improperly installed devices will not perform as intended and consequently, will not protect the equipment.  The conductor length between the SPD and the protected equipment should be a minimum of three feet in length to allow enough time for it to react. The conductors can be greater than 3 feet as long as they are isolated and are not subjected, or directly exposed to internally or externally-generated, transient voltage spikes and/or surges. Always make sure that the field wiring (unprotected wires) and the [...]

When evaluating surge protection for your networked devices, its essential to choose the right product to do each individual job. There is more to surge protection than simply hooking up a device – in fact there are several different types of surge protection, each engineered with differing core components performing the “dirty work” of dissipating surges away from your critical devices. The three most commonly found core components are MOVs, SADs, and GDTs; most surge protectors are built around one of these three and are defined by the capabilities of that component. There are also hybrid, multi-stage models available that [...]

  As an experienced HVAC installer, you may already be aware of the critical protection that surge protection devices provide for your customers’ HVAC systems.
