One studied alternating current (AC), and the other, direct current (DC). And yet, the world would not be where it is today without their contributions to science and electricity. In light of Nikola Tesla’s birthday on July 10, Mr. Electric is taking a look at the electric Tesla vs. Edison feud.

The main focus for Tesla was alternating current: an electric charge that periodically reverses its direction and is delivered to customers through a transformer. It travels at a much higher voltage than direct current and is more effective because of its ability to travel greater distances while maintaining a constant voltage.

Edison focused his research of electricity on direct current. A key difference between alternating current and direct current is that direct current only flows one way. The voltage of direct current is also constant but it is better when the electricity produced has to travel in short distances.

Edison was working on a system to generate direct current. When he could not get it to perform correctly he hired Tesla, an engineer and graduate of The Polytechnic Institute, who studied electromagnetism, promising him $100,000 if he could correct the problems Edison was having with his research and invention. Tesla corrected the problems but was not given the money. Tesla resigned and Edison spent the rest of his career trying to discredit Tesla’s research and work with electricity.

Today, nearly every home and business in the world is powered using Tesla’s alternating current. The ability of alternating current to travel over long distances and efficiently power everyday home and business electrical equipment eventually overtook Edison’s research on direct current. Edison did not lose out completely, as most battery-powered devices, fuel cells and light emitting diodes use direct current. As the push for alternative energy sources is on the rise, many manufacturers are looking at how batteries and electricity can change the way we look at fuel and the way goods are produced. Whether the electricity being used is AC or DC, Tesla helped us get where we are today.

If you’ve ever watched the show “Holmes on Homes” on HGTV, you’ve likely seen the problems associated with old or faulty wiring.  Mike Holmes tends to get very agitated by safety issues, and for good reason.  Each year, over 40,000 homes suffer fire damage due to home electrical problems.  These electrical fires account for hundreds of deaths and thousands of injuries.  And what’s the main culprit?  Old wiring!

If you live in a classic home built before 1940, chances are you have old wiring in the house.  You may have knob-and-tube or Romex wiring, both of which can become brittle over time.  The insulation dries out and starts to crumble, causing the inner wire to become exposed. The cloth insulation around the wire deteriorates with age and eventually becomes unsafe.

But perhaps one of the biggest threats of Romex and knob-and-tube wiring is that these types of wires aren’t grounded.  That means if one of your appliances shorts out, you could become the path to the ground for the electricity.

Even if your home is only 20 or 30 years old, you could still experience electrical problems at home due to a lack of capacity.  Most homes built more than 10 years ago are not designed to handle the amount of electronics we use today.  Think about it:  if your house was built in 1980, it was built before home PCs and laptops and HDTVs and surround sound and all of the other toys and gadgets we use today.  These appliances can draw a lot of power, and your current electrical wiring may not be up to the task.

If you own one of the one million houses in the DFW area that’s more than 20 years old, it’s a good idea to have a licensed electrician come out and take a look at the wiring.  He or she can make sure that your house will be safe and productive for many years.

It doesn’t feel like it yet, but fall is coming! Cooler weather and clearer nights are on the way; perfect time for some home hot tub relaxation. But when our electricians in Baltimore talk hot tubs, we have some concerns. These stem from various issues, but they can all mean one thing in the end: danger.

At Kolb Electric, your safety always comes first. Yes, even before our service (though you might argue that they go hand-in-hand; we would). If you’re considering a hot tub installation, or you’re just getting primed and ready to make use of the one you have, there are some factors we would like you to consider.

Looking for industry-leading electricians in Baltimore for your hot tub or home appliance wiring? Contact Kolb today!

The definition of the word faulty is “working badly or unreliably because of imperfections”, so when we’re talking wiring, faulty can mean old or damaged, or poorly installed. Both of these are equally dangerous and can lead to electric shock, electrocution, and fires! It’s serious business and we aim to help ensure you never deal with these potential threats.

So why are we so worried about hot tubs? Aside from the fact that they’re almost literally giant bathtubs with an electric current, once they’ve been installed many homeowners opt to never have the wiring inspected for water damage or replaced.

And even further beyond, some homeowners regard hot tub wiring as a DIY job. It’s really, really not. Wiring can get complex, and when you’re dealing with something as potentially volatile as electricity (especially when that electricity is surrounded you water!), even the tiniest mistake can become a harmful and even deadly issue.

So how do you get the glorious hot tub you’ve always dreamed of with none of the risks? Do these:

Hot tubs are made to be enjoyed, not worried over! When you’re ready for an installation, trust in the team at Kolb. Or if you’ve already got a hot tub, let our team make sure your system is working safely and effectively. Contact our experts today for the superior service and safety assurance you deserve!

Central forced air heating is by far the most popular kind of Zone heating, also called zone control heating, is a system of dampers installed in the ductwork of your home. The dampers are basically large valves that can open and shut to direct air flow. A damper is installed at each room junction, effectively splitting the house into a number of isolated zones. A thermostat is installed in each room with a damper, allowing that room total control over the air flow into it.

Zone heating is often installed to remedy the two problems mentioned above. Normal central air heating is inaccurate in which rooms it heats, so zone heating isolates each room to allow precise control over their climates. Central air heating causes a lot of uneven hot and cold spots, due to its reliance on a single thermostat. Zone heating compensates for this by installing many thermostats, ensuring that each room can be set to the comfort level of whoever occupies it.

By solving these two issues, zone heating saves energy and makes the rooms in your home more comfortable to be in.
