Tech Tips:

A few times in the past, we’ve heard the phrase “the house is the biggest duct” because of the way air moves through it. Well, we can take it a step further and see that there are similarities that go just beyond air movement. A building has several layers to keep things like moisture, heat, […]

Exposed Duct High Temperature Limit

I bought a crappy old house built in the 1920s a few years into my marriage. There were so many things wrong with it. Water intrusion, leaking pipes, roots in the sewer line… on and on. But it was our house, and we loved it. One issue was that the water heater was tiny, and […]

In this short podcast episode, Bryan answers a listener-submitted question asking whether you can use another surge protector at the disconnect panel with an ICM 493 already in place.

Using multiple surge protectors in the configuration described does NOT count as daisy-chaining. Surge protectors with MOVs (metal oxide varistors) shunt current from high voltage to ground by reducing their resistance. MOVs are sacrificial, so they wear out over time. Surge protectors don’t last forever, so installing multiple is a fine idea.

You can have whole-home surge protection with additional surge protectors positioned at the appliances/electronics. While it can be done and doesn’t hurt anything, it’s not the most cost-effective solution.

When you install a surge protector, wire it in parallel with the circuit to ground. It should be wired properly with the shortest possible path to ground. In any case, many surge protectors won’t hold up against direct lightning strikes, but they will protect the equipment from power surges after power comes back on or constant overvoltage.

Our company, Kalos Services, now uses DITEK’s Kool Guard 2 as our surge protector and voltage monitor of choice. They also provide warranties for their products, which have come in handy for customers.
