Electrical motors are devices that convert electrical energy into mechanical force. They operate on the principles of electromagnetism, using the interaction between winding currents and magnetic fields to generate force. Some motors, like those used in the transportation industry can reverse the effect and generate electricity too, converting force into electricity.

Many industrial plants attribute over 70% of their power consumption to motors, so even a slight increase in efficiency can dramatically cut energy spending and improve profits too.

Older homes have their charm, but as anyone living in one can tell you, they also come with more than their fair share of issues. Building and electrical codes have changed dramatically over the years, and our everyday electrical demands have continued to skyrocket. At Kolb Electric, we don’t want to discourage anyone from living in the home of their dreams.  That said, we do want people to be safe, so if you currently live in or are thinking of moving into an older home, here are some things you should be on the lookout for.

Electrical wires can function for a long time, especially if they haven’t been damaged and if the insulation hasn’t become brittle and flaked off. Even knob and tube wiring, an old standard for wiring that hasn’t been used in years, can still keep the lights on. Age does catch up with wiring eventually, however, and if the insulation fails, by becoming abraded, being chewed, or any number of other reasons, a short or electrical arc could start a fire.

Older homes often have wires surrounded with a spiral metal jacket. Metal-clad wires are still used today, especially in areas where the wire is exposed to potential damage. Armor-clad wires are distinct and do not have a separate ground wire within the metal sleeve, instead using the sleeve itself as the ground. As a result, for fire safety reasons, armor-clad wires are often barred in new construction.

If you can see obvious signs of a problem, including scorch marks on terminals in switches and outlets, missing or damaged insulation or any other signs that look potentially dangerous, you should call Kolb Electric for home rewiring before you expose your home to a live wire.

Restoring old chimneys and relining flues are common expenses of owning an older home. Here’s what happened: as coal started to become readily available, existing homes were retrofitted with central heating systems. Nowadays, most coal-fired systems have been converted or updated for oil or gas, but many are still vented into unlined chimneys. Where chimney liners are present, they are usually made of terra cotta and can rapidly deteriorate with higher-combustion, energy-efficient heating equipment.

When evaluating a heating system, make sure you consider its age, type, condition, and efficiency. For example, an old cast iron boiler may last a century or more, but updating to a more modern system can reduce your future heating and maintenance costs.

Old plumbing systems are notorious for being a mish-mash of old and new materials, especially as additions are added to the home or kitchens and bathrooms are remodeled. Iron and lead piping can become clogged with corrosion and mineral deposits, and typically need to be updated in sections. Cast iron piping is even worse, and can corrode from the inside, becoming thin, pitted, and cracked. Horizontal sections are usually the first to go—especially if chemicals drain cleaners containing sulfuric acid have ever been used.  Unless the home has already had repiping done, you can almost guarantee you’ll need to do it yourself.

Unless your roof is under 80 years old and / or is made of slate, you can bet it’s probably not original to the home. There are numerous types of roofing materials, all with unique life expectancies and maintenance requirements. Many older homes have multiple additions with roofs of different ages and types, so like the plumbing system, individual sections may need to be replaced.

If you’re moving into an older home, make sure you have it inspected thoroughly beforehand to make sure it’s safe. And if you need electrical maintenance in Maryland, Virginia, or Washington, DC, call Kolb Electric today!

The electrical field is one that has seen a number of remarkable discoveries over the decades. One very important lesson has been the aspect of grounding of electrical currents. It’s true that we need electricity for almost everything in our daily lives and can’t even imagine a world without it. However, it continues to be one of the most dangerous elements on earth. If you haven’t already properly grounded your home’s electrical systems, you are taking a significant risk by not doing so.

Every electrical circuit has an active wire which supplies power; there is also a neutral wire which is responsible for carrying the power back. There is a third wire (grounding wire) that can be attached to the power outlets & the electrical appliances and devices; this wire is connected securely to the ground in your breaker box.

This third wire is the additional path that the electrical current can pass through to be safely returned to the ground, in case there is a short circuit; this prevents any harm being caused to anyone. In the event that a short circuit occurs, the current flows through into this grounding wire and it’s when you notice a tripped circuit breaker or a blown fuse in the electrical main board on your property. If this wire hadn’t been grounded, it would have resulted in a fatal shock.

This is one of the most important reasons to ground electrical currents. It’s the best way to protect your family members from electrical surges when they are operating any electrical appliances in the house. In case a lightning strike causes an electrical surge on your property it can result in extremely high electrical voltages in your system. When the wiring has the proper grounding, all the excess electricity gets diverted into the earth, rather than burning everything that’s connected to your electrical system.

When your installation is grounded, it becomes very easy for the power to get directed exactly to where you need it; this allows the electrical currents to efficiently & safely travel across your home’s electrical system.

A properly grounded system makes it much easier for the power to be distributed in the right amount to the right places. This plays a significant role in ensuring that there is no overload in the circuits. The earth becomes the common reference point for all the different sources of voltage in an electrical system.

One of the primary reasons why grounding is extremely effective in keeping you safe is because the earth is an excellent conductor, and electricity always takes the path that has the least resistance. When you ground your electrical system, you are giving it a path that it can easily take, rather than into you; this can potentially save your life.

If your home’s electrical system isn’t properly grounded, you are just risking the appliances and equipment that are connected to your system, being burnt beyond repair. If the situation gets out of control that can also result in a fire risking your property and causing physical injury, sometimes even death.
