A: Unplug everything and turn off all the lights on that circuit. Then try to reset/replace the fuse/breaker. If it still does not work the problem is wiring and you should call an electrician. If the circuit resets then plug things back in and switch the lights on one at a time – if you plug something in and it trips the circuit the problem may be with the item you are using. If you cannot find the problem with this method, you should contact an electrician.

Frequently, issues that happen with knob and tube wiring are due to old fittings wearing out, or from some non-standard changes that were made to the electric system by either the previous owner, or by an unprofessional, unlicensed electrician. This typically occurred when additional outlets were installed combining new Romex cable with old K&T wire, which is like putting a square peg into a round hole.
Knob and tube wiring also has rubber insulation, which creates additional safety issues. As time passes, rubber erodes, exposing copper wires to moisture in the air, which significantly increases the chance of a short circuit, or a fire.
Another problem with knob and tube wiring is it’s limitation with load demands. Frequently, homeowners in need of extra outlets would hire electrical contractors to add extra outlets to the existing K&T wires. These additions create the danger of overloading the electrical systems, especially with today’s power-intensive appliances and devices.
Because there is no equipment grounding conductor present, the switch box and the light fixture are not grounded or bonded to the electrical system. This creates a real shock hazard.
One other dangerous condition to note, which is not visible in the photo, is the slop sink that is directly below the light fixture. Talk about a real shock hazard when your hands are wet!
A. Hot tub installations have surged in popularity over recent years. Water and electricity typically don’t mix well – which is why it’s extremely important that you have your hot tub wired by a qualified contractor. It’s important that you understand exactly what hot tub wiring installations involve in order to ensure that you are safe during the process.
Most hot tubs need a dedicated 240V, GFCI circuit to safely provide them with the power they need to run. To meet your hot tub’s electrical needs, you need to make sure your home is running on at least a 100 amp electrical service. Most homes built in the past 50 years or so meet this requirement, and many homes built more recently even exceed this, with 150-200 amp service. However, if you live in a historic home in the area, you may need to upgrade your electrical service before any hot tub wiring can be done.
If your home is ready for hot tub wiring, it helps to understand some of the guidelines that are outlined in the National Electrical Code (NEC), specifically ones dealing with hot tub installations. For instance, it is a violation of the NEC to install a hot tub under power lines. Additionally, you should avoid installing low-voltage lighting within 10 feet of your hot tub.
Electrical installations can be very dangerous for the novice, especially around water. There is a risk of shock or electrocution, which could result in serious injury or even death.
