Protecting homes and businesses since 1950, Guardian Protection is one of the nation's largest and most highly regarded security companies. We provide smart technology, 24/7 professional monitoring, and peace of mind to hundreds of thousands of customers. Our products are installed by experts, monitored by real people, and truly make a difference. We do what we do because of one simple truth: life is better when it's safe.

"We hired Guardian to install our security system at our Washington, DC, business. The service and quality of the work was horrible. We had cameras and an alarm system installed; it was a relatively large system. They outsource most of the work to various vendors. They could not manage their vendors; what was supposed to take a week took two months. The sales rep did not return calls, and you could never get anyone in management on the phone. Random people would show up at unannounced times. The few things that an actual Guardian employee did were they made a huge mess of our newly remodeled office and were rude to our staff. We have offices in five markets across the US and have high security at each; we have never had such a poor experience."

Electrical questions, answered by experts

A piggyback circuit breaker, also known as a tandem or double-stuff breaker, combines two separate circuits into a single slot in a breaker panel. This design allows adding more circuits without a larger panel, making it a space-saving solution. Each breaker in the piggyback unit operates independently, protecting two circuits in one standard breaker slot. This is especially useful in older panels with limited space for additional breakers.

In the United States, home outlets support a standard 15 amps, but you can upgrade per outlet if necessary. Most single-family residential homes have a maximum overall amp rating, usually 100 to 200 amps. Very old houses may have less than 100 amps, but that’s rare. Large homes often come with amp services above 200 amps to support modern lifestyles.

Yes, many providers offer wiring upgrades as part of their services. Confirm with your contractor.

Single-pole light switches are the most common light switches on the market. Their simple features make them easy to install and use. For more powerful applications that require 30 or 40 amps, you may need to use a double-pole switch. Some homeowners may want multi-way switches like three-way or four-way switches to control a light fixture from opposing ends of the room.

Volts and watts aren’t directly convertible units—they measure different aspects of electricity. Volts measure electrical potential, while watts quantify the power. The relationship between the two is defined by the equation: Power (watts)= Voltage (volts) x Current (amperes). In other words, the product of volts and amps results in watts, but there is no fixed conversion of volts into watts.
