Most homes spend more on plug-in strips over a decade than a single whole-house surge protector.
Most homes in Colesville, MD spend more on plug-in surge strips over a decade than they would on a single whole-house surge protector that does the actual work. The math isn't subtle.
A whole-house surge protector intercepts large voltage spikes before they enter the home's branch circuits. Together with quality plug-in protectors at sensitive devices, it provides layered defense.
1st Choice Electrical Services installs these properly across Colesville, and we'll explain the math out loud before you commit to anything.
At the service entrance (line side of main breaker). Highest clamping capacity. Ideal for storm-prone areas or homes with heavy electronics.
Standard residential install at the main panel. Excellent protection for most homes in Colesville against utility switching and induced lightning surges.
