In the US, electrical equipment and wire installations must adhere to the National Electrical Code (NEC) as a safety precaution. Every three years, it is modified; the 2023 NEC is the most recent version. We’ll go over the changes to surge protection in the 2023 NEC here for anyone who needs to know more about the new edition.
Surge protection is a crucial component of electrical safety, especially in the modern world when sensitive electronic devices are widely used. Many changes to surge protection are included in the 2023 NEC to enhance security and accommodate emerging technologies. Follow along!
1. Expanded Coverage
In the 2023 NEC, surge protection amendments extend coverage to various installations and equipment, including surge protector power strips and 20 amp surge protectors. This expansion recognizes sensitive electronic devices’ increasing prevalence and vulnerability to transient overvoltages. Previously, surge protection requirements may have primarily targeted critical infrastructure or specific facilities.
However, the 2023 NEC acknowledges the ubiquity of electronics in modern society, from residential homes to commercial buildings and industrial facilities.
The NEC aims to enhance overall electrical safety by extending surge protection coverage. They want to ensure that a broader range of electrical systems and devices are safeguarded against damaging voltage spikes.
2. Type 1 SPDs
In the 2023 National Electrical Code (NEC), there’s something called “Type 1 Surge Protective Devices,” or SPDs for short. These devices are shields for our electrical systems, especially the outdoor extension cord, protecting them from big electricity surges. These big surges can come from lightning strikes or when the power company switches things around.
When lightning strikes nearby or there’s a significant change in the power grid, it can send a tremendous wave of electricity through our wires. This surge can damage our electronic devices like computers, TVs, and even the wiring in our homes. That’s where Type 1 SPDs come in. They’re specially designed to handle these big surges and keep our electrical systems safe.
So, the 2023 NEC might have some new rules about how we use and install these Type 1 SPDs. These amendments may encompass guidelines on the placement and configuration of Type 1 SPDs. This could help optimize their ability to safely intercept and divert high-energy surges from sensitive electrical equipment.
All these rules ensure that our electrical systems stay safe and our devices stay protected, even when nature throws us a big electrical surprise. Even the best surge protectorsare at a colossal risk without following them!
3. Type 2 SPDs
Another focus is on Type 2 Surge Protective Devices (SPDs). These devices help protect your home’s electrical system from surges inside your house. This is unlike Type 1 SPDs, which protect from external surges like lightning.
Turning off a large appliance like an air conditioner or a refrigerator can send a little shock through your home’s electrical system, starting from your flat extension cord. These shocks are called internal surges. Over time, they can damage or even destroy other electronic devices in your house, like your laptop or TV.
Type 2 SPDs catch and neutralize these internal surges before they can do any harm. The 2023 NEC updates include more detailed guidelines on implementing these Type 2 SPDs. This means the rules are more specific about where and how to install them so they can do their job better, ensuring your electronics are safer from these unpredictable internal electrical spikes.
4. Coordination
Imagine you have several layers of security in a video game to protect your base. Some guards are at the gate, some are inside, and others are hidden around the perimeter. Each set of guards has a specific role in defending against different attacks. This idea is like “coordination” in surge protection in electrical systems.
To handle a specific surge or voltage spike, we employ a variety of Surge Protective Devices (SPDs) in the electrical industry. Type 1 SPDs address significant, outside threats like lightning. However, Type 2 SPDs can control small internal surges brought on by events such as shutting down a gigantic machine.
The SPDs are just like the SPT-1 vs SPT-2; only that while the SPTs are electric wires used for different applications are surge protective devices designed to safeguard electrical systems against voltage spikes and surges.
Ensuring that these many technologies coexist peacefully is the responsibility of coordination. The first device can be subjected to an excessive or inadequate load if not synchronized. This might lead to a system failure or permit some surges to get to the equipment, damaging it.
5. Bonding and Grounding
Electrical safety measures like bonding and grounding allow surges to be safely directed to the ground, averting shocks and fires. While bonding connects metal components to lessen the risk of shock, grounding provides a direct path for surges. The 2023 NEC strongly emphasizes bonding and grounding enough to guarantee that every component can resist surges. This enhances the electrical system’s dependability and safety, particularly during storms and lightning strikes.
6. Maintenance and Testing
Surge protection devices protect your electronics from potentially damaging electrical spikes. However, these devices must be checked every month to ensure proper functioning. The 2023 NEC, a thorough collection of electrical safety regulations, offers guidelines on how often to check, what to look for, and how to test this equipment.
This is crucial since these devices’ capacity to protect your equipment may diminish with time, and if they aren’t properly maintained, they might not be able to do so.
In summary
To provide more protection for our electrical devices against unforeseen voltage spikes, the 2023 NEC has updated its surge protection regulations. Higher standards for products that absorb these spikes are among the changes made, ensuring correct installation and upkeep to safeguard everything from your refrigerator to your phone.
