"This company is absolutely fantastic! Tony is so professional and a really great guy. He bid me a price for some work that turned out to be much more complicated than originally thought. He did not try and increase his price and did the work for the pre-determined rate. In addition, I had a tv he was supposed to hang that was brand new in the box. When he opened it, he discovered the screen was shattered. I was able to return the tv and he is coming back out on a separate trip to hang it. He has really gone above and beyond. I cannot recommend him more highly."

The modern suburban and small town home of today has become an ideal lightning target. The home owner would do well to recognize lightning for the destructive force that it is and protect against this major life and fire hazard. Donohue's Lightning Rods is based in Missouri, near the factory where most of the residential and commercial lightning rod supplies are manufactured. Jim travels regularly to Texas, Louisiana, Arkansas, Missouri, Kansas, Montana, Wyoming, Colorado, and New York. Call today to find out when Jim will be in your area. For installations outside Missouri, Kansas, or Texas, Jim waits until there are a few customers lined up, thus being able to provide the same quality services at affordable prices. **WE DO NOT DO ELECTRICAL SERVICES.** (ONLY LIGHTNING RODS)

"The job was beautifully and professionally done. I have a zero scape yard and the gentleman was concerned about disturbing the gravel when putting the rod into the ground. WOW!!!!"

Electrical questions, answered by experts

You don’t need to be an electrician to change a light bulb. You also don’t have to be an electrician to replace a light fixture with another compatible one. But, if you are installing a light fixture for the first time, it’s worth hiring a licensed professional for the job.

While a handyperson may charge a bit less, a qualified professional can make sure everything is up to code and working exactly as it should be. This is especially true for more complicated lighting projects.

The American Wire Gauge system calculates wire size diameters using the complicated formula D(AWG)=.005·92((36-AWG)/39) inch. A simpler rule of thumb is that every six-gauge decrease doubles the wire diameter, and every three-gauge decrease doubles the wire’s cross-sectional area. On the other hand, wavenumbers are typically measured in reciprocal meters (1/m or m−1) or reciprocal centimeters (1/cm or cm−1).

You can test an electric fence with a multimeter, but you’ll need to set the multimeter to the correct voltage measurement—such as alternative current (AC) or direct current (DC) and range—depending on your fence. You can find the voltage type and range in the fence’s user manual.

It’s a great idea to replace and update outlets, especially if an outlet stops working. New outlets work well with modern appliances and devices. Over time, outlets become old and worn—they can even become damaged, cracked, and burnt if the wiring is old and outdated. Old outlets and wiring can cause smoke, sparks, flickering lights, and an electrical fire.

The number of outlets you can run off one wire depends on the circuit's amperage and your local electrical codes. Generally, you can have up to eight outlets or light fixtures on a single 15-amp circuit. For a 20-amp circuit, you might accommodate more, but ensuring the total load is within the circuit's capacity is crucial. Always consider the power usage of connected devices to prevent overloading. Consult local electrical codes or a licensed electrician for precise guidelines and safety.
