Electrical questions, answered by experts

You shouldn’t try to touch the electric fence, as it will shock you. Typically, the shock is low enough to be uncomfortable to humans or animals that come into contact with the fence. But an electric fence with high voltage, or a faulty fence, could shock you and cause serious injuries when touched.

Track lighting typically needs to be hardwired, connecting directly to the electrical wiring in your ceiling for a permanent and reliable power source. Hardwiring provides a clean and professional look with no visible cords. However, plug-in track lighting options can be connected to a standard electrical outlet, offering easier installation and flexibility. The choice between hardwired and plug-in track lighting depends on your needs, preferences, and existing electrical setup.

While not always necessary, wiring your circuit breaker in a certain way can ease both the installation process and use afterward. For starters, you’ll need to install the electrical panel so that the main service knockout aligns with the cable conduit. If they aren’t aligned, you may not have sufficient working space to finish running the wires. Using cable trays, on the other hand, gives you a bit more freedom to and flexibility in where and which direction you install the wires. At the end of the day, the power flow will be the same whether the cords run up or down.

Yes, wire connectors are the better option for securing splices compared to electrical tape. It is not recommended to use electrical tape as it is not secure enough to keep the splices together. Plus, electrical tape is more vulnerable to damage, which can cause a risk of fire over time. 

A faulty light switch can trip a breaker due to circuit overload or a short circuit. A faulty light switch may not always trip a breaker, so don’t use that as your only sign that something’s wrong. Always investigate the cause of a switch that isn’t working properly, feels hot to the touch, or is making unusual noises.
