Thunderstorms pose a safety hazard in several ways. Lightning is the most dangerous part of a thunderstorm, and it kills more people than hurricanes and tornadoes combined. Thunderstorms produce heavy rain, which can cause flash flooding. The strong winds from a thunderstorm can also cause widespread damage. Each of these components requires specific precautions to minimize their danger.

A thunderstorm typically has a diameter of 15 miles and lasts for 30 minutes, which is much smaller than a hurricane or winter storm. The National Weather Service places specific criteria on a severe thunderstorm. These include thunderstorms that produce hail with a diameter of at least ¾ inch, wind gusts of at least 58 mph or a tornado. Severe thunderstorms comprise about 10 percent of all thunderstorms.

The NWS recommends that you stay indoors for 30 minutes after the last clap of thunder when you hear thunder less than 30 seconds after the lightning. This rule is known as the 30/30 lightning safety rule.

Avoid taking emergency shelter in structures that are vulnerable to high winds, such as a mobile home. Outdoors shelters such as sheds, pavilions and golf’s typically will not protect you from flying debris and lightning. Avoid and report downed power lines. Bring pets and livestock under shelter to protect them during hailstorms.

There’s no question that LED lights are the best option for fleet vehicles—or any vehicle for that matter. They consume 90 percent less energy than incandescent bulbs and last about 42 times longer. Because fleet vehicles are constantly in motion, long-lasting LED lights can be of extreme benefit to trucking companies. A longer life span means dramatically lower maintenance and replacement costs as well as a reduction in downtime.

We have LED lights for Peterbilt, Kenworth, Freightliner, Volvo, International, Mack, and Western Star trucks as well as box trucks, tow trucks, dump trucks, and more. Options include LED tail lights, LED brake lights, LED marker lights, LED reverse lights, and LED clearance lights. These truck lights are available in a wide variety of styles, shapes, sizes, intensities, and connector types. Take a look through the categories below to see some of what’s available, and visit the links for complete product lists.

All of our LED truck lights meet DMV FMVSS 108 requirements and are protected by a lifetime warranty to guard against manufacturer defects and malfunctions. Mounting accessories are available under the accessories tab on each product page.

Options include multi-function combo boxes. Rear combination lights can be mounted vertically or horizontally on either side of box trucks, tow trucks, dump trucks, trailers, and flatbed trucks. The all-in-one lamps can be used as tail lights, brake lights, parking lights, turn signals, reverse lights, and running lights. Light heads can be rearranged for customized positioning.

Multi-function combo box lights have red and white LEDs and can be used as rear reflex reflectors, turn signal lights, hazard warning lights, reverse lights or backup lights, brake lights, and tail lights. Separate LEDs are positioned on the bottom of the box for license plate illumination.

Mechatronics, or mechatronic engineering combines mechanical and electrical engineering to design innovative products and systems. These systems must rely on mechanical and electrical components working together in harmony.

The list includes DVD disc drives, anti-lock braking systems, manufacturing, electric motors and clothes dryers, among others. These devices require electronic controls and feedback systems to interact seamlessly with their mechanical design.

Motor control systems operate by using a programmable logic controller or PLC. This system allows advanced programming and algorithms to dictate a motor’s behavior. Therefore, they can be programmed to control multiple motors or VFDs. A robotic arm or a large factory machine is a good example of this.

In addition, PLCs can accept inputs from a wide range of sensors and switches. This allows precise feedback from the machine it controls. Furthermore, it executes built-in software.

The smallest high-precision motors, DC motors, found in computer hard drives and DVD readers. Due to their miniaturization, they can be easily controlled by computer software to perform nearly any imaginable task. A battery powered quad-rotor drone offers us a prime example of DC motor control. Accelerometers and gyroscopes feeding data into a computer controller adjust the speed of each motor independently to keep the drone flying level.

A simple technology that combines electric motors with feedback control, known as servomechanisms, provides valuable information. They utilize a small electric motor, gearboxes, and a potentiometer to produce accurate position feedback to the motor itself. This ensures that the motor has moved to the correct position. Thus, precise movement control of a motor is possible. Applications of servos include RC car steering, fly-by-wire systems in aircraft, robotics, and industrial control valves.

Servos communicate with computer systems, allowing them to be part of larger mechatronic systems, so they can be controlled by PLCs and computer algorithms.

The field of mechatronics constantly evolves. Therefore, as it does, it incorporates cutting edge computer software and mechanical design, bringing to life new inventions. These breakthroughs make modern-day living much easier and more fun.

If improperly installed, aluminum wiring can raise the risk of a house fires! From 1960’s up to the mid 1970’s aluminum wiring was sometimes used for branch circuit wiring instead of copper wiring.  During this time period copper prices were very high and aluminum wiring became a cost effect alternative to copper wiring.  Was aluminum wiring found to be as good as copper wiring?  Not even close!  Aluminum wiring quickly became a fire risk if not installed properly.  At the time aluminum wiring methods were exactly the same for copper.  Over time it was found that improper installation methods and electrical devices not designed to accept aluminum conductors could lead to fires.

If was quickly found out that aluminum wiring could cause flickering lights, hot electrical connections and even burned or melted insulation on the wiring.  There was a severe problem with overheating which can lead to fires.

1.  A Softer Metal.  Aluminum is a much softer metal when compared to copper.  During the stripping process from aluminum it can be easy to nick.  These nicks can cause hot spots in the conductor causing overheating and the potential risk of fire.  Electricians had to develop different methods of stripping the insulation off of the aluminum wiring to avoid damaging the conductor.

2.  Aluminum Expands.  When an appliance demands electricity on the circuit the conductor heats up.  While this process takes place with copper conductors too aluminum expands at a much greater rate than copper.  This expansion and contraction of the aluminum wiring  caused the the conductor to creep out from under the terminal screws on breakers and electrical devices such as plugs and switches.  This creeping of the wiring resulted in a loose connection which lead to sparking and potential fire.

3.  Corrosion or Rust.   When steel rust it becomes red, on copper rust is green, and on aluminum it is white.  When copper wiring rust it’s not as big as problem when compared to aluminum, copper rust is actually electrically conductive.  This rust on copper still allows the electricity to flow and doesn’t create as much resistance of the electricity or simplify put it doesn’t interfere as much.  However, when aluminum rust it forms a white oxide which is not a good conductor of electricity.  This creates resistance or reduces the flow of electricity.  This resistance interferes with he flow of electricity, and can cause overheating leading to fires.

There are several options for you if you have aluminum wiring in your home.  We can evaluate your homes wiring and come up with several effective methods and affordable price ranges.  It’s important to have your homes wiring thoroughly evaluated so you can know the truth about its condition so you can make the proper decision.

Solution 1.  Rewire the entire house with copper wiring.  This would be the safest long term solution for aluminum wiring.  This method would require reduced maintenance and reduced inspections needed when compared to aluminum wiring.  Rewiring the home is the safest long term solution to aluminum wiring when compared to other methods.  This solution can be expensive when compared to other solutions.  However, we have a variety of financing options and payment plans available for almost every budget.

Solution 2.  Check all connections in home and repair as needed.  Then re device the entire home with aluminum rated devices.  This short this method entails replacing all the homes plugs and switches with ones that are designed to accept aluminum conductors.  It’s important to note aluminum rated devices can be hard to find at the big box stores.  When these devices were first introduced they simply had a larger screw or terminal for the aluminum conductor to fit under.  Unfortunately, these CU/AL devices failed to work good enough and was not an effective solution.  New devices CO/ALR are created out of a similar metal which shares a similar expansion and contraction rate as aluminum which reduces the creeping of the conductor.

Solution 3.  Pigtailing.  Pigtailing simply means taking the aluminum wire connections that go to the device and splice on or pigtail on a copper conductor to go to the device such as a plug or a switch.  It is important to note that it does take a specially designed wire nut or twist-on wire connectors to to perform this method.  While this method is the cheapest it is important to make sure that routine safety checks and inspections are performed on your homes wiring to reduce the chances of future problems.

Even with all the disadvantages, aluminum wiring still has its advantages under certain applications.  It’s important to note even with these advantages you should not use aluminum wiring in your home for standard 15 or 20 amp branch circuits.

1.  It’s Light Weight.  Aluminum is lightweight in nature.  Being lightweight is an advantage when conductors are used over long distances.  This lightweight property is most beneficial for aerial applications were the aluminum wiring is suspended between poles.  This wiring method is most commonly seen in utility company applications and telecommunication lines.  Being light weight also makes the aluminum wiring easier for the installer to work with.  This makes the cable less physically demanding to install.

2.  Aluminum Wiring is Cheaper.  Aluminum wiring can be half the cost of copper wiring.  When a large amount of wiring is needed saving half the cost can be a huge benefit over copper wiring.  This method is mainly seen in feeder circuit applications in commercial buildings as well as sub panels and 220 circuits in residential applications.  It’s important to note this practice of using aluminum wiring for sub panels, services, and 220 circuits in residential applications has been deemed acceptable when properly installed and connected.
