Type 1 vs. Type 2 Home Surge Protectors
When you’re looking to protect your home from lightning strikes and excess electrical current, you’ll need to invest in the right types of surge protection for your home’s circuitry, appliances, and devices.
Surge protectors, also called surge protective devices (SPDs), surge arresters, or surge suppressors, shield your electrical system from sudden energy spikes that can fry your wiring and electronics, shock people inside, and start fires. These overloads can be caused by a variety of events, including:
- Direct or indirect lightning strikes
- Utility grid transformer switching
- Electrical accidents
- Power restoration after an outage
- Large home appliances turning on and off
- Short circuits inside your home
What Are the Different Types of Home Surge Protectors?
Gainesville residents need to protect their homes against external and internal electrical threats, and there are two types of surge protectors designed to do the job. Each has specific characteristics that protect against different kinds of overloads.
Type 1 Surge Protectors
When you need to protect your whole house from large electrical overloads during events like direct lightning strikes and utility transformer switching, you need a Type 1 surge protector. These devices provide a first line of defense against external, high-power energy spikes before they reach your electrical system and prevent potential damage to your circuit breaker, wiring, and connected devices.
Type 1 surge protectors work by intercepting sudden, large 25 kA-200 kA energy surges using a 10/350 µs waveform. These devices are rugged, with weather-resistant housing to withstand the outdoors, and they can operate even if your main breaker is off. An electrician can install this type of surge protector on the line side of your circuitry, between your utility pole and your home’s main service panel.
Type 2 Surge Protectors
To protect your home against residual currents and electrical faults inside your house, you need a Type 2 surge protector. These devices use an 8/20 µs waveform to neutralize 20 kA-40 kA surges within your home’s circuitry. They protect your sensitive electronic equipment from power fluctuations caused by short circuits, bad wiring, or large appliances turning on and off, and they also provide a second line of defense against external surges by reducing leftover current.
Type 2 surge protectors can increase the lifespan of electronics like computers, entertainment systems, smart devices, and appliances. They are typically constructed for indoor use and mounted directly into your electrical panel on the load side after your main circuit breaker.
Which Surge Protector Should You Choose?
A surge protector’s effectiveness depends on its use case. Each type plays a different role in defending your electrical system from external and internal surges, so neither is inherently better. Type 1 devices are particularly useful in areas like Gainesville that carry a high risk of experiencing lightning strikes and heavy surge currents. They can handle extremely powerful surges, but since they don’t completely block residual current from traveling through your circuitry, you also need to install a Type 2 device for full protection.
Together, these devices can prevent major damage from lightning strikes, electric system malfunctions, or short circuits and potentially help you save thousands of dollars in repair and replacement costs. Both types of surge protectors will usually last 5 to 10 years unless they are hit by a direct high-energy surge. Running periodic diagnostic tests on your surge protectors will ensure they are functioning properly.
Why You Should Hire a Professional to Install Your Home Surge Protectors
When you’re making improvements to your home’s electrical system, it’s important to have an experienced electrical contractor assess your specific needs. Installing surge protection safely and efficiently requires working near high-voltage lines, understanding waveform signals, grounding the system correctly, and meeting local, UL, and National Electrical Code standards. Improper installation can create hazardous conditions in your home and increase the risk of damage to your electrical system. Selecting the appropriate surge protection requires:
Risk Assessment
Assessing your surge protection needs accounts for several factors, including Gainesville’s weather patterns and utility grid setup. Your electrician will consider your risk of lightning exposure and fire, calculate the value of the equipment inside your home, and estimate probable downtime after a large electrical surge to determine the level of coverage you need.
Technical Considerations
When you’re investing in some surge protection, your devices need to be matched to your electrical system’s voltage. Your electrician should ensure that your surge protectors have the appropriate short circuit current rating to handle a fault current. Your surge protection devices should also provide comprehensive protection against several types of electrical spikes and have low voltage protection ratings (VPRs) to protect your most sensitive equipment.
