Whole Home Surge Protection: Protecting Your Electronics and Appliances
Power surges damage electronics and appliances worth billions annually. Learn how whole-home surge protection works and...

AJ Long Electric installs compatible panel-mounted surge protective devices after reviewing service and panel configuration, device ratings, conductor path, grounding and bonding, status indicators, and local permit requirements. Surge protection reduces risk but cannot stop every surge or guarantee equipment protection.
Overview

A panel-mounted surge protective device can reduce exposure to certain transient overvoltage events before they reach downstream equipment. It is one layer in a broader protection strategy that may also include effective grounding and bonding, compatible point-of-use devices, and protection for other service paths. A surge protective device cannot completely prevent every electrical surge or guarantee that connected equipment will not be damaged. AJ Long Electric evaluates the service and panel configuration, available connection method, conductor path, grounding and bonding, device type, short-circuit rating, and manufacturer instructions before recommending a scope. The completed installation includes labeling, status-indicator review, and an explanation of the homeowner checks specified by the equipment maker.
A compatible device can divert certain transient overvoltage events at the electrical distribution point.
Device type and ratings are matched to the service or panel configuration and listed instructions.
Visible grounding and bonding conditions relevant to the installation are evaluated as part of the scope.
The homeowner learns how to read the installed device's normal and replacement indicators.
The proposal explains that surge protection reduces risk but does not guarantee equipment protection.

DMV homes can have overhead or underground services, multiple panels, detached structures, generators, EV equipment, and sensitive electronic controls. Surge-protection planning should follow the actual distribution system rather than assume one panel device covers every path or event.
How It Works
The documented process moves from assessment and scope definition through authorized work, testing, and closeout. Timing and coordination are confirmed for the property and approved scope.
We document the service configuration, panel compatibility, available connection method, and visible grounding and bonding.
Type, ratings, enclosure, instructions, conductor requirements, and placement are matched to the system.
The proposal identifies included equipment, connection work, limitations, and any related corrections.
The approved device is connected with the required protection, conductor routing, labeling, and clearances.
Operation is checked and the homeowner reviews status and replacement guidance for the installed model.
FAQs
Get answers to common questions about our surge protection services.
A compatible panel-mounted device can reduce certain transient overvoltage events at the electrical distribution system. Performance depends on the event, device, installation, conductor path, grounding, bonding, and the equipment being protected.
A surge protective device cannot completely prevent every electrical surge or guarantee protection from a direct or nearby lightning event. It reduces risk as one part of a layered electrical protection strategy.
They may be appropriate for specific equipment as part of a layered strategy. Point-of-use products must be listed, correctly used, and coordinated with equipment instructions; ordinary power strips are not automatically surge protective devices.
Many devices use indicator lights or another status display. We review the specific manufacturer's indicator and replacement instructions because the meaning and maintenance steps vary by model.
Only the insurer can decide coverage, claims, eligibility, discounts, or premium effects. Product warranty terms, if any, are set by the manufacturer and should be reviewed directly.
Requirements depend on the address, connection point, and whether the work is part of a larger panel or service project. We confirm the local permit and inspection path for the defined scope.

Common Problems
Learn about common electrical issues and when to call a professional.
Two-prong ungrounded outlets are common in older homes but lack the safety grounding that protects people and equipment. Several upgrade options exist depending on your home's wiring.
Learn MoreLight bulbs that burn out too quickly can indicate voltage problems, fixture issues, or simply low-quality bulbs. Identifying the pattern helps determine the cause and solution.
Learn MoreStorm-related power loss in Northern Virginia is usually one of three things: a Dominion Energy grid event (out of your control, fixed by the utility); damage to your service entrance (the wires + mast + meter base, which we coordinate with Dominion to repair); or surge damage to your panel and downstream devices (which we repair without utility involvement). The first step is to check the Dominion outage map; the second is to call us if there's visible damage at your home.
