Fans in the attic? The idea at first may sound odd. We usually think of fans as blowing somewhere in our home where we can feel their effects, like hanging from ceilings or mounted in windows. Few people spend more time in their attic than they absolutely must, so it seems useless to install fans there.

However, attic fans can form an important part of maintaining the overall efficiency of your air conditioning system. If you’ve taken all the steps you can to keep your HVAC system working its best (regular maintenance, duct cleaning, changing the filter, proper insulation), attic fans will take you a step beyond. We’ll explain why putting in attic fans will benefit you.

Attics are both heat traps and heat escape routes. You can use insulation to stop heat from escaping in winter, but what about summer, when heat gathers in the attic and creates excessively high temperatures that will seep into other parts of your home? (Go up into your attic on a hot day and see what it’s like. It can be miserable. You don’t want any of that to get to rooms you actually use.) To stop summer attic heat, you’ll need attic fans.

Attic fans should be wired to a thermostat that will turn the fan on based on the temperature. This saves energy since you won’t have to keep the fan on constantly or continually check on it. The movement of air in the attic will lower the high temperature.

The first benefit is the most obvious: your home will not get as hot during the summer. On average, the temperature in the attic will decrease 50 degrees with a fan, which means a drop of 10 degrees in your house.

This not only translates into comfort, it also means savings on your energy bills. A cooler house requires less work from an air conditioner to cool it. You’ll spend less, and your air conditioner will not receive extra stress that will lead to repairs and possibly an early replacement.

Attic fans will also extend the life of your roof. Rising moisture in your home will get into the roof, eventually creating mold in the insulation and the roof material. In winter, the freezing moisture can be extremely damaging. Attic fans move moisture away and keep it from settling.

If you live within the city of Los Angeles or even in the surrounding suburbs, you have probably been privy to a power outage a time or two. They can be a real drag if you are not prepared. Having a flashlight and candles handy is great, but wouldn’t it be nice to be able to simply turn on the light like you normally would when you wanted to read or find something in the cupboard? You can do just that when you have a generator installed by a Los Angeles electrician like those at The Electric Connection.

Standby generators ensure you have a source of power even when the main electric grid is down. You may not want to admit it, but our worlds revolve around power. Nearly everything we do requires electricity. Without it, we are kind of brought to a standstill. Fortunately, most power outages are short-lived, but an outage that extends more than an hour starts to become very bothersome. You are unable to do some of the simplest things like, warm up food, wash the dishes, do a load of laundry or even charge your electronics. Those batteries will only last for so long.

Having a standby generator is an investment you will certainly appreciate when the rest of the neighborhood is sitting in the dark. They go a long way to providing comfort and security. There is little work for you to do when the power goes out if you have a generator installed by an electrician. Los Angeles residents will have a switch installed on the generator that automatically switches the home from the power grid to the backup generator. You may have to reset a few clocks, but other than that, you can keep doing what you normally would. If you are interested in having your home equipped with a generator, give The Electric Connection a call today.

When you are purchasing a home, it goes without saying that you want to be sure the house is structurally sound, and that there are no lurking problems that will surface later and burn a hole in your pocket. It’s why many people get a building inspection and pest inspection done before they sign on the dotted line. While all of this sounds good, what most people aren’t aware of is that they can and should get an energy audit done too.

An electrical audit analyses the major components of the house structure; this includes:

In short, it gives you a very detailed picture about how the buildings works as a whole. For a couple of hundred dollars, you can get an energy audit done from a professional. This audit can save you a significant amount of money in the long term; it identifies the features in the house that require correction to enhance the energy-efficiency. At times, the energy audit results can play a pivotal role in your decision of whether you should invest in a particular property or not.

If you find that a house lacks in energy efficiency, but you still want to buy it, the audit results can become a bargaining tool; it may help you get the seller fix the problem, or you may be able to get the property at a much lower price. No matter which way you look at it; getting an electrical audit is a very good idea. In addition to the ones mentioned above, there are a number of other benefits to getting an electrical audit done, such as:

The simple fact is that spaces that are energy-efficient are also more comfortable to live in. Energy-efficiency upgrades will ensure that the heat will be evenly distributed across the home and your home will be warm in the winter and cool in the summer.

If the indoor air quality in your home is poor, it can cause allergies as well as other health problems. When you choose to get an electrical audit done, the professionals that are conducting the audit, carefully analyse the ventilation in your home and also recommend what can be done to improve the indoor air quality.

Energy efficiency may seem like an isolated aspect in the sustainability of your home. But when discrepancies in the building structure come to the fore during an energy audit, it’s indicative of the fact that many features are constructed poorly and that they will fail before their time. Once you have the audit results, you will get a clearer idea about what will have to do be done to improve the building envelope as a whole.

When you are hiring the services of an electrical/energy auditor, you should keep in view the fact that not every one of them uses the tools and follows the required processes while the audit is being conducted. Ideally, the auditor should use tools such as a duct blower, an infrared camera as well as a blower door.

The blower door is essentially a fan that has to be mounted on the doorframe. It efficiently depressurises & pressurises the home to measure what the air leakage is like. The duct blower performs the same function, but is attached to the ducting in the house. The infrared camera helps detect air leakage in the walls and the heat losses too.

Cold weather and winter storms are often to blame for power outages. It seems like when you need your heater the most, it will be rendered useless by a power outage. The power may go out for a number of different reasons. An accident, a severe storm or mechanical failure are all possibilities. You never know what may happen. A Pasadena electrician has some tips for you to keep handy just in case the power goes out this winter. If you have any more questions, you can always call The Electric Connection.

• Unplug your small appliances, computers, Smart televisions, gaming systems and any other items that have sensitive electrical components. Leaving items plugged in could damage them when the power comes back on. A small power surge can fry the electrical components. You can reduce or eliminate this risk by having a whole home surge protector installed by an electrician. Pasadena residents can save themselves a great deal of money on damaged appliances with one of these inexpensive tools.

• Call the power company hotline to determine how long the outage is expected to last.

• Shut the doors to any rooms you are not using to keep the heat in one area. Put on extra layers of clothing to stay warm.

• Pull out flashlights and candles if the power outage happens in the evening. Emergency candles are different than the typical decorative candles and will put out more light.

• Instruct everyone in the house to leave the refrigerator and freezer doors closed. Your food will stay cold for 4 hours in the fridge and up to 24 hours in the freezer.

If the idea of dealing with a power outage does not thrill you, you could always invest in a standby generator. These handy tools will keep your home powered and allow you to continue on with your life without any interruption. Give The Electric Connection a call today to learn more.

constant-current LED driver or constant-current driver is used to regulate the amount of current that is supplied to an LED or LED array to maximize LED lifetime. If current is not regulated, LED brightness can fluctuate and life span can be shortened. The constant-current driver is used for LEDs or light fixtures that require a stable output current and operate within a range of voltages. Most finished LED products already have a constant-current driver or resistors to regulate current. If you’re building an LED fixture or replacing a constant-current driver, it’s important to verify that the output current and voltage of the driver is compatible with the LEDs’ current and voltage. If your LED product already has a constant-current driver or uses resistors in the LED array, you might need a constant-voltage power supply.

If your LEDs are dimmable and you want to change their brightness, choose a Magnitude Dimmable Power Supplies. These dimmable power supplies work by varying the power on the AC input side of the power supply by means of a TRIAC dimmer. This change in power on the AC input side will vary the voltage on the DC output side and control the intensity of the LEDs. TRIAC dimmers are common hardware store and household dimmers, which include brand names such as Lutron and Leviton.

Pulse-Width Modulation Dimming: Pulse-width modulation (PWM) dimming can be used to control dimmable power supplies such as Mean Well LPF Series. This type of dimming control adjusts the output current based on the duty cycle. As the duty cycle increases, current will increase and the LEDs will be brighter. Conversely, if the duty cycle decreases, the current will decrease and the LEDs will be dimmer. Pulse-width modulation for these drivers is based on a 10-volt signal level with a frequency between 100Hz-3KHz. The MLD-5A are compatible for this application.

Resistive Dimming: Resistive dimming can be used to control dimmable power supplies such as 12-Volt Mean Well HLG-40-240 Series or 12-Volt Mean Well HLG-600 Series or here.

The efficiency of a power supply or driver indicates the percentage of power that goes toward making your LED product function. An efficiency of 80 percent or higher is recommended for operating LEDs. 

When choosing a driver or power supply, the size of an LED product’s housing or area of installation is important. If you wish to put a constant-current LED driver inside of a product, the driver must be small enough to fit in the product’s housing. Similarly, if the driver or power supply is used outside of the product’s housing, it should fit the area of installation. Drivers and power supplies are available in a variety of sizes to suit your needs.

A Class 2 driver or power supply is in accordance with limited power levels defined by the National Electric Code (NEC) and fulfills the requirements of Standard UL 1310. Output is limited to 60 volts DC and 100 watts. Because power sources with this rating have limited output, it might not be possible to power as many LEDs or lights as those that don’t have a Class 2 rating. However, these power supplies and drivers provide protection from fire and electric shock.

A Class II rating refers to a double insulation layer between AC input and DC output wires. These drivers and power supplies do not require a ground connection.
