How the New NEC Surge Protection Code Affects Electrical Panel Upgrades and New Construction in Northeastern Pennsylvania

Surge protection is now required by the National Electrical Code. Not optional. Not recommended. Required.

For the new 2020 NEC code changes it is required that all residential service upgrades replacements and new service installations have Type 1 or Type 2 surge protection installed. This requirement did not exist before 2020. It applies to every panel upgrade, service replacement, and new construction electrical installation across Northeastern Pennsylvania.

What Changed in the NEC and Why It Matters for NEPA Property Owners

The National Electrical Code is updated every three years. Pennsylvania adopted the 2020 NEC in July 2025 making it the current standard for all electrical installations across the state including Northeastern Pennsylvania.

While surge protection requirements first appeared in the NEC code in 2002 surge protection did not become mandatory until the 2020 update. That is a significant shift. For the first eighteen years that surge protection appeared in the NEC it was guidance. Since 2020 it has been a legal requirement for the specific installation types the code covers.

The code committee statement regarding the new code section expressed that this code change addresses the need for surge protection to properly protect the sensitive electronics present in most modern appliances as well as safety devices including AFCI GFCI and smoke and carbon monoxide detection and other equipment commonly found in dwellings.

That reasoning matters for property owners in NEPA. The NEC did not add this requirement because surge protection is a nice feature. It added it because modern properties are filled with electronics and appliances that are increasingly sensitive to voltage spikes. HVAC control boards. Smart appliances. Security systems. EV chargers. Fire alarm control panels.

Which Projects in NEPA Now Require Surge Protection Under the NEC

This is the practical question most property owners ask when they first hear about the NEC surge protection requirement. The answer depends on the specific type of work being done.

Electrical panel upgrades and replacements

Article 230.67 now requires all services supplying dwelling units to be provided with a surge protective device as an integral part of equipment or located immediately adjacent. The SPD must be a Type 1 or Type 2 SPD.

If you are upgrading your electrical panel in a NEPA property from 100 amp to 200 amp service, replacing an aging panel, or replacing a fuse box with a modern circuit breaker panel the NEC now requires surge protection to be installed as part of that project.

New construction

Every new home and commercial building constructed in Northeastern Pennsylvania under the 2020 NEC requires surge protection installed at the main electrical service. This applies to new construction of single family homes, multi-family residential buildings, hotels, motels, dormitories, nursing homes, and any other occupancy type listed under the updated code requirements.

Section 230.67 required either a Type 1 or Type 2 surge protection device for all services supplying dwelling units. This requirement includes both new construction and replacement equipment such as service changes or upgrades.

Service replacements after storm damage

When a storm damages electrical infrastructure in NEPA and a service replacement is required as part of the restoration work the NEC surge protection requirement applies to that replacement installation as well. A service replacement triggered by storm damage is treated the same as a planned upgrade under the code.

What Type 1 Type 2 and Type 3 Surge Protection Devices Actually Mean

Understanding the three types of surge protection devices helps property owners in NEPA understand what they are getting and why the NEC requires specific types for specific applications.

Article 230.67C of NEC 2020 and 2023 specifies two types of SPDs and recommends the use of at least one of them for whole house protection. Type 1 SPDs are installed before the main device in the load center while Type 2 SPDs are positioned on the load side.

Here is what each type means for your NEPA property in practical terms:

Surge Protection Devices

Devices are the highest capacity surge protection available for residential and commercial installations. They install before the main breaker in your panel and can handle the largest surges including direct lightning strikes to utility infrastructure. Article 230.67 stipulates that SPDs shall be an integral part of the service equipment or shall be located immediately adjacent thereto. SPDs are devices that safely intercept and discharge power surges and spikes to ground before overvoltage can damage valuable electrical equipment.

Surge Protection Devices

Devices install on the load side of the main breaker inside or immediately adjacent to the panel. They are the most common type installed during panel upgrades and new construction in NEPA because they satisfy the NEC requirement and are compatible with virtually all residential and light commercial panel configurations. SPDs shall have a nominal discharge current rating of not less than 10kA. This minimum rating ensures the device can handle significant surge events not just minor voltage fluctuations.

Surge Protection Devices

Devices are the point of use surge protectors that most NEPA property owners are already familiar with. Power strips with surge protection. Plug-in surge protectors at individual outlets. These devices do not satisfy the NEC panel-level requirement on their own but they serve an important secondary role as a second layer of protection for the most sensitive electronics in your property.

To get complete surge protection coverage getting both Type 1 and Type 2 installed is recommended. For the new 2020 NEC code changes it is required that all residential service upgrades replacements and new service installations have Type 1 or Type 2 surge protection installed.

What the 2023 NEC Added Beyond the 2020 Requirements

The 2023 NEC expanded the surge protection requirements beyond what the 2020 update established. While Pennsylvania is currently operating under the 2020 NEC understanding the 2023 additions helps NEPA property owners plan for what is coming in the next code adoption cycle.

In addition to the clarity of SPDs in dwellings NEC 2023 added section 409.70 requiring the placement of an SPD to be internal or immediately adjacent to control panels that support personnel protection.

The 2023 NEC added surge protection requirements in Section 215.18 for dwelling units supplied by a feeder. Apartment complexes hotels motels and nursing homes are typically supplied by an electrical service that in turn supplies through a feeder other dwelling units or sleeping units. Requiring surge protection for feeder supplied dwelling type units ensures that the SPD is closer to the load where the sensitive electronics need the protection.

For commercial property owners in NEPA operating multi-tenant buildings hotels or healthcare facilities the 2023 NEC expansion means that individual unit panels and feeder supplied panel locations will require surge protection in the next Pennsylvania code adoption cycle. Planning for that requirement now during current renovation or upgrade projects is more cost effective than retrofitting after the new code takes effect.

Older commercial buildings will have to update or replace existing infrastructure to maintain compliance which could prove costly depending on the electrical systems. Newer dwellings will lessen that impact as most have adhered to the 2020 NEC codes which outline the required electrical panels outlets surge protection and appliance guidelines.

What This Means Before Your Next Electrical Project in NEPA

If you are planning a panel upgrade service replacement or new construction project in Northeastern Pennsylvania here is what you need to understand before work begins.

Surge protection is not an optional upgrade your electrician is trying to add to the job. It is a code required component of the installation that must be in place before the project passes inspection. A panel upgrade completed without the required surge protection device installed at or adjacent to the panel does not fully comply with the current Pennsylvania electrical code.

For many improvements including new circuits panel upgrades and EV chargers you must use a licensed electrician. DIY work may not pass inspection and can void insurance or resale value. A licensed electrician can inspect your home and give you a list of recommended upgrades to meet the current NEC standard.

Before any panel upgrade service replacement or new construction electrical project begins in your NEPA property confirm with your electrician that the surge protection device required under the 2020 NEC is included in the scope of work and that it meets the minimum 10kA nominal discharge current rating specified in Article 230.67.

We serve residential and commercial properties across Scranton, Wilkes-Barre, Throop, Dunmore, Archbald, Moosic, Olyphant, and the surrounding Northeastern Pennsylvania region. Every panel upgrade and new construction electrical installation we complete includes the NEC required surge protection device as a standard part of the project because that is what current Pennsylvania code requires and what your property deserves.

Code Compliance and Real Protection Working Together

The NEC surge protection requirement exists because the code committee recognized that modern properties are filled with sensitive electronics that unprotected electrical systems cannot adequately defend against the surge events that storm-prone states like Pennsylvania create every season.

For NEPA property owners a panel upgrade that includes properly installed surge protection at the panel level delivers two things simultaneously. It brings the installation into compliance with current Pennsylvania electrical code. And it provides the whole-property surge protection that the electronics appliances and safety systems in your building actually need to survive the next Pennsylvania storm season intact.
