A modern convenience often taken for granted, electric power, can be found everywhere. To route electricity from the power station to your wall outlet requires many steps. Residential house wiring includes a variety of wiring and control devices to ensure safe and reliable service.

Electricity in the home is distributed by means of branch circuits. Furthermore, each branch circuit is supplied via a circuit breaker sized per the expected load on the circuit. A typical lighting and receptacle circuit will be rated at 15A. Because of their size, larger loads like ovens, clothes dryers, and air conditioning units are given dedicated circuit breakers.

A typical home can have dozens of 15A circuits, and several 20A, 30A, or even 50A circuits. Yet the total of all these breakers is much more than the size of the main breaker. However, this is intentional. It’s highly unlikely that every circuit will be fully loaded at any one time, so a demand factor is taken into account to keep the main breaker at a reasonable size.

A wood-framed home will typically use solid copper non-metallic sheathed cable for the majority of wiring applications. Solid conductors are easy to terminate and cheaper than equivalent stranded wire. The AWG size of the wire is determined by the expected load on the circuit and by the size of the breaker protecting it. You should never connect a wire to a breaker that is too large to protect it, as an overloaded wire can easily catch fire.

The storage of renewable energy for business and homes, and it’s applicability as a renewable energy solution is often seen as a daunting prospect, but solutions are now available that truly bring this “next generation” technology to a level that can be easily implemented and understood.

Renewable power needs to be broken down into individual applications and needs. Not everyone cares about promoting technology and advancements, but by taking steps one at a time, we accomplish two things. One is education on possibilities, and two is further development on technology. Here is my idea on awakening society at a level most people can comprehend until other options become refined and perfected.

Storage of renewable energy with Wind and Solar for daily use:

Photovoltaic and Wind technology together make this really cool. When you add power storage with renewable energies, these automatic transferred units can be programmed to “sell back” electricity when electrical demand and storage capacities are satisfied. All of this is programmable in any order/sequence desired. By putting the units side by side, these systems can produce 240 volt single phase or three phase power with a pure sign wave.

Here is a great example of a real world solution that we call the Power Cart. This example utilizes solar panels, yet wind power could be added to the system very easily. This Power Cart system provides 20,000 watts of usable power, rechargeable through 4 solar panels, offering any home or business the ability to create, store, and use their own renewable electricity on a daily basis, and maintain power in the event of an outage.

Power Cart

Power Cart will have a Continuous Output of 3.6KW with a 9KW Surge start. This 48 volt grid interactive Outback power plant has 60 amp input/ output, and a UPS 60 amp transfer switch. It works from batteries, generator, or grid and can be charged by sun, wind or any type of generator or from the utility grid. Recharge can be programmed to take advantage of these in any order or percentage you desire. It is internet programmable and monitorable taking over 400 screens in excess of 10,000 commands – including the most important one ‘Let me work on automatic and don’t bother me.’ Also included is complete DC protection from the array to the charger, and from the batteries to power plant& AC protection via 60 amp breaker outlets (wired per country – as per order) also available in any output voltage ex. 100-150 volt, in 50 or 60 cycle.

Power Cart is a 4 wheel trailer – Ready to Work. No assembly required

These can be daisy chained for more production, more voltage, more storage.

It might be hard to believe, but even with as cold as it’s been, spring is on the way! And while you’re out enjoying the outdoors, the Sterling electricians at Kolb Electric want to bring you some electrical safety tips to make this spring safe and fun!

Keep power cords away from water – you probably already know this, but water and electricity don’t mix. Any time you’re dealing with electricity, make sure you’re working in a completely dry environment. You should also consider testing your GFI outlets.

Beware of power lines – if your spring cleaning involves getting up on a ladder or using a long-handled pool-cleaning tool, make sure you know you’re clear of power lines before you start. Power lines are interesting—if you were to hang from one without your feet touching the ground, you would be safe. However, coming into contact with power lines while you’re standing on the ground is a different story, as the electric current will travel through you on its way to the ground. Note that if the power lines are low enough, this could happen even if you’re just standing under them!

Always call before you dig – underground power lines are just as dangerous as overhead power lines, and since you can’t see them, it’s almost impossible to know where they are! If your spring plans involve digging of any kind, like adding an addition to your home or even planting a tree, make sure you call to confirm that it’s safe to do so!

Keep materials, tools, and all body parts at least 15 ft away from overhead lines – like we said above, power lines can strike you even if you’re standing too close to them. 15 ft is the safest minimum distance, so make sure you’re aware of this, especially if you’re working on the roof.

Never fly kites or model airplanes near power lines – we keep harping on the power line issue because they can be very dangerous if you’re not careful. If you have a kite or model airplane that ends up getting tangled in power lines, don’t try to get it down yourself—call your local utility provider for assistance. As a side note, make sure you never use any metallic materials in your kite—these can conduct electricity back to you.

Inspect power tools and electric lawn mowers before every use – frayed power cords, broken plugs, and weathered or damaged housings can make your equipment dangerous to use, so don’t use anything until it has been repaired properly. When not in use, keep these tools unplugged and store them in a dry area.

Watch out for power lines hidden behind foliage – before you trim tree limbs and shrubs, make sure there are no power lines hiding behind them. If you are concerned about tree limbs growing on or around overhead power lines on your property, call your local utility provider.

Keep your electrical box clear – you know that large, green, ground-level box you may have in your yard? That box houses the components of an underground electrical system. Keep it clear of vegetation and other permanent structures, as utility workers may need to access the underground lines and equipment during unplanned outages or routine maintenance.

Do not use electric mowers on wet grass – as we said in the beginning, water and electricity are a dangerous combo. Only use an electric mower on dry grass, and if you need to use an extension cord, make sure you use an insulated cord designed for outdoor use and with the correct power rating for your equipment.

Treat all power lines the same – some power lines are high voltage, some are low voltage. For safety, treat all power lines as if they are harmful—because chances are, they will be!
