A microwave is basically standard in any home these days, along with refrigerators, washing machines, etc. But do you know very much about your microwave? Furthermore, is it important that you know anything about your microwave? You might be surprised by our answer!

At Kolb Electric, our experts make a point to stay up to date with any and all information regarding modern electrical practice, the workings of appliances and how they impact your home. Why do we tell you this? So you know we know our stuff when we say wattage is the single most important factor in choosing a microwave! Well, that and a popcorn button.

Avoiding the potential (and boy, is there potential) for a massive science lesson, wattage boils down to a unit of measurement for a unit of power. In how your average person understands it, wattage is how much power an appliance utilizes to operate.

Microwave wattage generally spans between six and twelve hundred (600-1200) watts. You can see the wattage of your microwave on either the original package, or on the bottom of the unit. It will either have a number and say watts beside it, or it will simply have a number and a “w”, which means watts.

Understanding the wattage of your microwave tells you a few things. In a practical sense, it tells you how strong the microwave is. This is why “cook times may vary”. It also tells you what your microwave needs to operate smoothly. Many microwaves require a dedicated circuit to operate smoothly. We’ll go further in depth on this in a moment.

But, why have varied microwave wattage?

Well, there are a few good reasons. Many homes and older building simply can’t handle the supply need of higher wattage appliances, thus lower wattage options are available. Additionally, larger or more powerful microwaves are (naturally) more expensive. So, there’s a practical reason, and a cost-based reason.

What was that about a dedicated circuit?

Many homeowners feel that just any old outlet will do for their microwave. Most of the time, they learn they’re wrong the hard way. Microwaves require a dedicated circuit because it’s code and legally required, and  because not having a dedicated circuit can lead to breaker flips, power surges and permanent appliance damage.

Microwaves are high-power items, and use some of the highest wattages in your home. Furthermore, they use energy in a very intense way, which means a microwave can stress your circuits like no other.

We hope you learned something useful (or at least a little interesting)! Do you know if your microwave is on its own, dedicated circuit? If not, contact a Kolb professional today!

Modern buildings, commercial spaces, and even homes increasingly implement advanced building automation and control technology to improve energy efficiency, user comfort, and extend the life cycles of equipment.

At the core of any building automation system, or BAS, remains a central computing hub. This is where software processes the variety of signals it receives from connected sensors, switches, and user inputs. In a typical home, a Wi-Fi network connects devices wirelessly. Further, it will often connect them to the internet, allowing remote access from any web-connected device.

The only real difference between homeowner systems and commercial applications is scale. A large building can have many more devices and sensors connected, but the core function remains the same. The primary focus of commercial systems, however, is energy efficiency over user convenience.

In a large building or factory, even a small percentage of energy savings can have a huge benefit, not only in lower utility costs but also in reductions of CO2 emissions. With an efficient BAS, a building can attain a LEED (Leadership in Energy and Environmental Design) rating, which is a measure of energy efficiency and low environmental impact in building design.

As technology advances, the potential risks grow for building automation. Each day, more devices become connected to the internet. This is now referred to as the “Internet of Things”. The ease and convenience increases, but so does the potential reward for hackers. Anything controlled by the user or by software could potentially be taken over by a malicious hacker.

It is vital that digital security remains a priority, especially in a home setting. Many smart devices are not as secure as they may seem and are often only as secure as the home’s Wi-Fi network. Some good first steps include changing your Wi-Fi network’s password to something unique. Use the latest encryption protocols and enable MAC address filtering, which allows only devices specifically approved to connect to the network.

Building automation systems will continue to grow in ability and convenience. As long as the potential risks are managed, the possibilities for energy efficiency and user comfort remain nearly endless.

Maintenance Factor

Illumination Systems are designed to fulfill the required lighting level at the end of an operation term and not at day one of the new installation. The luminous flux of the system is going down over lifetime. This is a normal process, no product is lasting forever but the required illuminance levels should not be depreciated at any time. If a lighting system is setup, the maintenance plan has to be fixed too. So the facility managers know how often to clean the room, the luminaries and how frequently to change lamps. A reasonable time needs to be found between maintenance and operating hours, as maintenance cycles are connected to costs. The longer the operation time without maintenance, the more luminaries need to be installed to guarantee the required illumination level at the end of the term. The more frequent the maintenance cycles, the higher the maintenance factor, but also the related costs for the facility service.

Which Points are influencing the Maintenance Factor? Different factors influence the decrease in lighting level like the soiling of the room surfaces, the soiling of the luminaries, depreciation of luminous flux by the light sources or lamps failure.

Room Surface Maintenance Factor: The room surface maintenance factor is the ratio of the room surfaces reflectance before and after cleaning. It is the reduction of the lighting level according to soiling of the room. Luminaire Maintenance Factor: The luminarie maintenance factor is the ration of the luminaries luminous flux before and after cleaning. It depends on the luminarie construction and design (open housing or closed one) as well as on environmental conditions (dirty or clean). Lamp Lumen Maintenance Factor: The lamp lumen maintenance factor is the ration of luminous flux at a specific time compared to a new lamp. It is describing the aging of the lamp or the reduction of light intensity over time. Manufacturers offer comprehensive tables about their lamps luminous flux behavior. Lamp Survival Factor: The lamp survival factor depends on the service lifetime of a lamp. Some lamp lifetimes are reduced by frequent switching. The lamp manufacturers provide tables indicating the lamp survival factor. If a lamp is not working any more, the decision for immediate replacement or group replacement needs to be taken. If the lamp is replaced immediately (mostly in areas where the luminaire is easily reachable) the LSF can be set 1. On the other hand, the decision could be to replace lamps in special terms or group-wise. This could be the case in huge halls, where machines need to be stopped to reach the luminaires.

A maintenance factor of 0.8 shows, that the new lighting system needs to be over driven by 25% not to undercut the minimum required illumination level after 10 years. LED lighting systems are flexible and easy to connect to control systems. The installed load will provide efficient luminous flux at the end of the operation time but the energy that is “over” in the beginning can be saved. The new installation would illuminate an area with required 300lx by about 450lx. The energy can be saved by lighting management systems that are regulating the power concerning the luminous flux depreciation. HID lamps are not easy to control. The energy load that is “over” in the beginning is wasted. No change to save it.

Conclusion: Think carefully when setting up a lighting installations maintenance plan. This starts already with the choice for the light source. LED Modules are efficient, likely not failing and offer long lifetimes between 50,000h and 100,000h. The control possibilities are comprehensive. The luminaries overload, that needs to be installed to guarantee the end of lifetime illuminance levels, can be saved by light management systems. Regarding all the mentioned points, LED is the competing light source. The features are dominant over traditional light sources. Take the chance and install or renew your lighting system by  energy efficient LED light sources and luminaries.
