Compressor Defender™ by Intermatic?

To prevent future surge impairment, I had an electrician install a whole-house surge protector at the main electrical panel.

In 2015, lightning struck a tree in my daughter's neighborhood. The surge damaged several electronic devices. The cost to replace the Internet modem, Goggle box and home theater receiver totaled slightly less than her $1,000 homeowner's insurance deductible, so she had to bear the entire cost.

To prevent hereafter surge impairment, I had an electrician install a whole-house surge protector at the main electrical panel. Then I installed plug-in and hardwired surge protector receptacles at each of her electronic devices and appliances. Simply I was stumped as to how to protect her home'due south key air conditioning (A/C) unit.

I was especially concerned virtually her A/C because her neighborhood sometimes experienced rapid power failures, where the lights would flicker for a fraction of a 2nd. I know that kind of rapid Off/On cycling tin can be really difficult on the A/C's compressor, causing it to restart against high pressures. That strain can overheat and damage the compressor motor windings.

I plant a few surge and short-bicycle protection devices on the Net. Only the installations seemed complicated. They required swapping out the existing relay and mounting additional components inside the tight space inside the condensing unit. So I found the Compressor Defender™ product from Intermatic®. It's a surge and short-cycle protection device that likewise includes brownout protection (when voltage drops besides low during height electric usage in the neighborhood). The short-cycle feature senses power flickers and "times out" the compressor long enough to permit system pressures to equalize before restarting. The brownout feature works the aforementioned fashion, shutting off both the compressor and the condenser fan when it detects voltage that's likewise low for condom operation, then restarting the motors when proper voltage returns.

The best part is that the Compressor Defender™ costs virtually $fourscore (Intermatic #CD1-024RK at lowes.com). Plus, it'southward much easier to install than the other products I plant. Just mount information technology to the disconnect box on the house and splice in two wires inside the condensing unit of measurement.

Three wires, 30 minutes, and information technology'south done

I turned off the A/C's circuit breaker and flipped off the ability switch at the furnace. And so I opened the encompass on the outside disconnect box, removed the inner cover and double-checked that the ability was off using a voltage sniffer. It was off, and I was good to go.

Next, I removed a knockout on the side of the disconnect box, fed in the wires from the Compressor Defender™, and secured it with the locknut.

Then I routed each of the ii black wires upwardly to the screw terminals marked 'LINE.'

I cutting the wires to length, stripped the insulation, inserted them under the screw clamps and tightened them. I secured the white wire from the Compressor Defender™ to the grounding/bonding coach. That was it for the disconnect box, so I put the covers back on.

Using goose egg ties, I secured the low-voltage cablevision to the conduit running from the Compressor Defender™ to the A/C condensing unit.

Then I removed the condenser unit of measurement's access cover and spliced the low-voltage cablevision from the Compressor Defender™ in serial with one of the A/C control wires coming from the house. I reinstalled the access cover and turned on the ability.

The greenish low-cal lit upwardly on the Compressor Defender™ and the Air conditioning fired upwards when I lowered the temperature at the thermostat. The unabridged Compressor Defender™ installation took less than 30 minutes.

Now all her electronics are protected against power surges, and her expensive A/C system is protected against the three most common electric risks.
