Type 1 & Type 2 SPDs • UL 1449 Listed • Panel-Mounted • Licensed & Insured • (239) 888-8888
Southwest Florida experiences some of the highest lightning strike frequency in the United States — and every lightning strike within miles of your home can cause a power surge that damages appliances, HVAC systems, televisions, computers, and smart home devices. Utility switching events from FPL during restoration after storms also generate significant transient voltage surges. A whole-house Surge Protective Device (SPD) installed at your main electrical panel is the single most effective way to protect every circuit and every device in your home from surge damage.
Captiva Island properties are among the most unique and valuable in Lee County. ElectriciansX serves Captiva homeowners with the same licensed, permitted quality as our mainland clients. Homeowners throughout Lee County are increasingly prioritizing surge protection after experiencing appliance and electronics damage during hurricane season power fluctuations. A panel-mounted SPD protects every circuit in your home simultaneously — unlike point-of-use power strips, which protect only the devices plugged into them.
Type 1, Type 2, and combination SPDs — we select the right device for your panel and service entrance.
The most common residential SPD — installed directly at your main electrical panel. Protects every circuit in the home from surges entering through the service entrance and from internally generated surges.
Installed before the utility meter at the service entrance. Provides the first line of defense against surges entering from the utility line — including direct lightning strikes to nearby distribution lines.
For maximum protection, we install both a Type 1 SPD at the service entrance and a Type 2 SPD at the main panel — a two-stage approach recommended for high-value electronics and HVAC equipment.
Detached garages, pool equipment panels, and outbuildings benefit from a dedicated SPD at their sub-panel to protect equipment from surges traveling through feeder conductors.
SPDs have a limited surge capacity — after absorbing significant surges, they need replacement. We inspect, test, and replace worn or failed SPDs with properly rated new units.
Not sure what protection you have? We audit your existing surge protection setup and recommend improvements based on your panel type, connected equipment, and risk level.
We assess your main panel type, available space, and service entrance configuration to select the correct SPD model for your installation.
We choose a UL 1449 4th Edition listed SPD with appropriate surge current rating (minimum 40kA recommended for Southwest Florida), LED status indicators, and a warranty.
A Type 2 SPD connects to a dedicated 2-pole breaker in your main panel, or connects directly to the bus bars if panel space is limited. We install per manufacturer specifications.
We power up the SPD and verify all LED status indicators confirm proper installation and protection is active.
Many premium SPDs include an equipment protection warranty covering connected devices. We assist with warranty registration documentation.

A whole-house surge protective device (SPD) is a device installed at your main electrical panel that detects transient voltage surges and diverts the excess energy to ground before it reaches your appliances and electronics. Unlike a power strip surge protector (which only protects plugged-in devices), a panel-mounted SPD protects every circuit and device in your home simultaneously.
A whole-house Type 2 SPD installation typically runs $300–$600 including parts and labor, depending on the SPD model selected and your panel configuration. A Type 1 + Type 2 two-stage installation runs $500–$900. Premium SPDs from Square D, Siemens, and Leviton include equipment protection warranties worth significantly more than the installation cost.
A Type 2 SPD is installed at the main panel on the load side of the meter — it protects against surges that have already entered the home through the service entrance. A Type 1 SPD is installed at or before the utility meter on the line side — it provides the first barrier against surges from the utility grid, including lightning-induced surges on distribution lines. For maximum protection, installing both types (two-stage protection) is recommended.
The primary causes of damaging power surges in Southwest Florida are: (1) lightning strikes — Florida leads the US in lightning strikes per year; (2) FPL utility switching events during storm restoration; (3) large motor start/stop cycles from HVAC compressors and pool pumps within your own home; and (4) utility line damage and re-energization after outages.
Most homeowner’s insurance policies cover surge damage from a direct lightning strike with documentation. However, smaller surges from utility switching events — which cause cumulative damage to electronics and HVAC over time — are typically not covered. A whole-house SPD prevents this damage from occurring in the first place.
For critical electronics like TVs, computers, and home theater equipment, using a quality point-of-use surge protector in addition to your whole-house SPD provides a two-stage defense: the panel SPD handles the large initial surge, and the point-of-use device filters residual voltage spikes. For standard appliances (refrigerator, washer, dryer, dishwasher), the panel SPD alone is typically sufficient.
