The type of in-wall wiring and cables you choose for your home will largely depend on what kind of signal you need to carry, where you’re going to route the wire, and how far the signal will have to travel between your various peripherals. Whatever type of wiring you choose to go with, you want to be sure you get one that’s rated for in-wall use by the Underwriters Laboratory (UL). This is usually going to be indicated with a CL2 or CL3 rating when it comes to speaker wire and audio/video cables. A good number of Ethernet cables are rated for in-wall use as well, usually indicated with a CM, CMR, or CMP rating. When choosing the right rating for each specific type of wiring, the UL looks at a range of different factors, including the heat being generated from current flowing through the wire, how quickly the cable will catch and spread fire when exposed to flame, and the wire’s vulnerability to damage from external stresses.

It is also important to look for a cable that’s rated for your specific needs. For instance, you are going to want cable that is rated as CL2P or CL3P if you are planning to run it in your heating ducts, or if you are looking to run your cable underground to connect to your outdoor speakers, you will want to make sure your cable is rated for direct burial. It should also be noted that when you are making the decision of what custom wiring you will need for your home, you need to be aware of your local fire codes and make your selections accordingly.

When you are looking for the right type of speaker wire for your home, there are two things you need to factor into your decision: the gauge and number of conductors. The gauge of wiring you choose should depend on how far the wire is going to have to travel from the receiver to the speaker. Significant power loss can occur over long runs of wiring, reducing your system’s performance. This might not be a significant issue in a single-room setup, but it is something to keep in mind if you are looking at a multi-room system. In terms of conductors, speaker cable comes with two or four. Two should be all you need for wiring a single speaker, but if you are looking at doing a multi-room setup, or a system with volume controls, you will mostly likely want four.

No home wiring setup would be complete without a solid Ethernet setup, but knowing which type of wiring to use can be a little confusing. When you are looking to create a wired computer network in your home, or carrying audio/video and control signals all across the home, CAT-5 cables have been the standard for a long time, but a better option these days might be to look at CAT-5e or CAT-6 cables. These newer cables are able to pass more data along the wire at a much faster rate than the older wires. The CAT-5e and CAT-6 wiring options are also backwards compatible with devices that were designed to work with the older CAT-5 wiring, meaning you won’t have to buy all new equipment. Ethernet cabling actually stands up to interference better than almost all audio/visual cables, which is a large reason it has become so popular in recent years for whole-house audio/video systems. It can also be a more cost-effective option to run long lengths of Ethernet cabling than it can be to run the same length in audio/video cable.

You’ve packed the swimsuits and the sunscreen, the bug spray and the camera, but did you remember to properly lock up and secure your home? While making that long vacation “to-do” list, don’t forget to include the proper safeguarding of your home on your list before you head off on your summer getaway.

If you’ll be away from your home for an extended amount of time, you might want to consider hiring a house sitter. Someone actually living in your home can help keep it safe from thieves, and your house sitter can also water your plants, retrieve your mail and newspapers, mow your lawn, or even take care of your pets while you’re away. And because your home will continue to look lived-in, it can hold less of an appeal to burglars. Hiring a house sitter is not the cheapest option for home security, but it can solve many problems at once and it is likely to be a solution that will give you the most peace of mind while you are away from home.

Nothing says “I’m not home” more than yellowed newspapers on your doorstep and mail overcrowding your mailbox. If you’ll be leaving your home for an lengthy holiday and if you don’t have someone you can ask to retrieve your mail and newspapers each day, you can ask for a stop delivery on both. The United States Postal Service will stop delivery and will hold your mail for up to 30 days for free, and you can either cancel your newspaper subscription or choose a stop delivery on your newsprint for however long you’ll be away. All you have to do is ask, whether in person or possibly even online.

With social media and online networking an ever-present entity in modern times, it’s easy to want to brag about your upcoming cruise or your month long road trip across America to all your online friends and family. But you may be unwittingly letting criminals know when your home will be an empty and easy target. Keep in mind that online information can be read by anyone, often even if your accounts are private, and you probably don’t want the entire world knowing that your property and home will be unattended during your vacation.

Don’t make your home a tempting target for possible criminals. Remembering to secure your home while you’re away can help keep your home and property safe, as well as help relieve any possible worries you might have so that you can actually relax and enjoy that much-needed vacation.

Solar Farm

From science fiction to massive solar plants in the American West, solar energy has fascinated and tantalized scientists and writers for generations.  The promise of easily-accessible, virtually free energy from the large fusion reactor at the center of our solar system (the sun) is enticing and we’re getting closer to harnessing its power effectively every day.

Solar power is interesting because it’s one of the few electrical energy systems that does not use a turbine to generate energy.  Photoelectric cells contain a material that releases electrons when hit by a photon, generating electrical power.  There are no moving parts, no fuel to burn and pay for, and only occasional maintenance to keep the system performing optimally.

So what is holding back the proliferation of solar energy?  Space and storage.  We can generate large quantities of energy from solar, but we do not, at present, have the right method to store that energy for periods without sunlight (night time and storms).  So far the best response has been homeowners installing solar cells on their own homes with battery storage systems linked into their own neighborhoods.  By splitting up generation and storage within the neighborhood itself, enough solar cells can be installed to generate energy both day and night.

Space is at a premium when it comes to energy generation.  Solar power plants take up more space than traditional plants, while generating less energy per square foot.  Because solar cells need to be placed over large areas to maximize sunlight, installing power plants in urban areas can be difficult.  Though installing solar cells on your home can be done simply.

We mentioned self-starting or “œblack-start” energy systems.  These systems can be started without power applied to the system, a huge benefit to fuel-fed power plants, and necessary in the event of major blackouts and power losses.  True, we can supplement with gas turbines or nearby power generation, but we also want black-start renewables.  Fortunately, hydroelectric power plants require no off-system power to function.

Hydroelectric plants are special because, while they also have a somewhat variable energy source, they also have one of the best energy storage systems available: potential energy.  Hydroelectric dams use flowing water to spin turbines, typically generated from lakes and rivers.  Rather than storing generated electricity, hydroelectric plants can store water at a higher altitude.  By storing water in special tanks, they have access to electrical generation potential by simply releasing the stored water and allowing it to spin the turbine.  Hydroelectric power is perfect for energy storage, but they’re limited to specific areas.
