Brook Livin WIRECARE AC Circuit Tester by The Gans


Brook Livin | ZEROPLUS is an interesting Taiwanese company that makes a great set of ZEROPLUS Logic Analyzers. On Sep/2021, Brook Livin also makes other products, and have a subsidiary that makes Smart Home Devices. Brook Livin recently sent me their new WIRECARE.

About 20 years ago we were renting a house, an old house. The wiring was perhaps to code, once, but clearly didn't conform to the Modern Electrical Code. I smelled Smoke and called the Fire Department who found nothing wrong. But they were less than happy to see how in the office I had Multiple Outlet Strips plugged into each other to support an Engineering Lab on the Single Outlet in the room.

As houses get older, all too often their Electrical Systems don't Get Upgraded. Very old places may have been refitted with wiring that's External to the Walls. Others might use Knob and Tube Wires, which scares me but I'm told is still legal in many jurisdictions. Here's an example:


The WIRECARE is a small device that evaluates the Wiring in Houses and Buildings. It's a pretty simple unit: you plug WIRECARE directly into an outlet and a series of LEDs flash for a couple of seconds before stabilizing on a color. Red means call an Electrician, now; Orange indicates Sub-Par Wiring and Green indicates everything is Copacetic.


Brook Livin WIRECARE is shown as 3 stages of Lights, and its correlation to the Impedance Value.

- In light of Red: Do NOT use the socket, and please arrange the repair / replacement ASAP

- In light of Orange: Pay attention to the socket, and please arrange the repair / replacement

- In light of Green: The socket is good to use, and please measure the Impedance with WIRECARE regularly, recommended at least half of year in every Socket / Extension Cord at home and business

When we moved into the current house 12 years ago, I ran 220 to a new Circuit Breaker Box in the garage and then circuits throughout the room. I plugged the WIRECARE into the circuit physically the most distant from the building's main breaker box and was happy to see it indicate green, an OK message.


Though our house is 50 years old, all of the circuits tested were green. Wanting to see it indicate a problem I connected it to the far end of a 100 foot extension cord that uses 14 gauge wires. And, voila! The WIRECARE's LEDs showed Orange, I suspect as a result of Impedance value through that long run.


At just $100 the WIRECARE seems like a nice way to be sure Your Circuits are Safe at Home and Business. Especially now that we too often employ outlet strips galore to support our electronics zoo.
