The pool at your Tampa home is an excellent place to enjoy recreation, to relax, or even to host events and parties. But are you getting the most out of your pool design? The use of light can add not only dynamic appeal to your space, but provides a greater level of safety. Not to mention the fun of a nighttime pool party!

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.

If you’re in the midst of a renovation or simply rearranging your floor plan, then you’ve likely come across the need to add or relocate a light fixture. Maybe your new dining room table is a little wider than the old one, you’re adding a kitchen island with pendant lights, or you’ve finally convinced your significant other to let you get that pool table you’ve always wanted. In any case, you need to move or add a light fixture – but how and when?

First, it should be noted that, contrary to how it may seem, most light fixtures are not connected to a joist or even drilled into wood. Instead, hanging light fixtures and ceiling lights alike are located between joists and supported by electrical boxes that grip a wide surface area of the sheetrock that makes up your ceiling to support the weight of the fixture below; for heavier fixtures, like large chandeliers or ceiling fans, there are larger, even joist-secured boxes that will need to be used.

If you’re moving a light fixture, it is important to note that there are certain limitations as to where the fixture itself can go. If you wish to relocate the fixture to a place where a joist exists just above, then you’re likely going to have to use a swag hook and chain to anchor the fixture in place, as a box under a joist is not an option. That said, if you’re moving the housing for the fixture itself, you’ll need to know which direction the joists above run, then choose to move it either through the same joist cavity or drill through a joist to run the current wiring to the new housing. Other things to consider include which switch controls the light and where it is located, as it is a safe bet that a wire will have already crossed all joists above (at some point). This can prevent your electrician from drilling needlessly by allowing them to fish the wire back to the earlier point. If your switch is further away than the destination, you can bet they’ll have to do some drilling. Jumping through, between, and around the joists in the ceiling represents the largest obstacle your electrician (and light fixture) will face.

Once your location is set, all that is left is to get your electrician out to assess and perform the work for moving your box. If you’re planning on doing one large fixture over a pool table, island, or entire room, then you’ll want to take into account the power output of the fixture compared to what that circuit can safely allow for as well as the weight of the fixture. A typical rule of thumb is that anything under about 35 pounds can be handled by a standard drywall box, but something more (or with a fan) will need extra stabilization. Surprisingly, if you’re running numerous small pendant lights, the electrician may have an even easier time running the circuit and ensuring that your lights are up and running in no time. Just be sure to discuss the fixtures you have in mind with your electrician before you purchase them to know what they believe your limitations are!

Modern day living is highly reliant on the use of electricity and the different appliances, equipment and fixtures it powers. Industries are even more reliant on electricity and their profitability is closely knit with how seamlessly their systems operate. They rely on electricity to such an extent that they rarely give it a second thought; well, at least not until something goes wrong such as:

Most of these problems can be attributed to poor power factor. Let’s understand a little more about what that is.

Power factor is essentially a measure of how effectively the incoming power is being used by the electrical equipment on your premises. It is expressed in terms of a numerical value in the range of 0-1. A higher power factor indicates that the electrical equipment is being used more effectively.

For instance, if the power factor is 0.8, it indicates that 80% of the power supply to the equipment is being utilised effectively and that 20% is being wasted. Regardless of what this ratio of effective usage Vs wastage is, the latter is an unnecessary expense. Typically, your power factor should be closer to 1; it indicates that your site is using energy in an efficient manner.

A number of businesses are currently being charged a kVA tariff and not a kilowatt tariff. This means, your service provider is probably charging you for the power they supply to you, rather than that you actually use. Simply put, you are paying for power that is being supplied to you, but which is being wasted. If your business has a low power factor, it means you pay even more for this waste. There is another aspect you should keep in view. As mentioned at the start, poor power factor has the potential to cause power drops and power losses; in turn, these lead to motor failure and overheating and failure of other equipment too.

Installation of Power Factor Correction equipment might just help avoid prohibitively expensive infrastructure upgrades; it does this by reducing the current electrical demand on your system & improving the efficiency stability. Based on which tariff you are on, power correction might just prove to be an excellent way for your business to deescalate its electricity costs.

The power factor can be improved by installing Capacitor Banks. These are PFC (Power Factor Correction) equipment and help correct the inefficiencies in the energy supply. Apart from this, they also reduce the peak demand on the power network. This is an effective and cost-effective solution to reduce your power bill as it helps lower the monthly demand and the capacity charges. Generally, the payback periods for PFC are between 1 and 3 years. Taking the life span of the PFC equipment into consideration & the potential savings, this investment can prove to be very worthwhile for you.

If you feel that you are paying too much for electricity, we at Allround Electrical can conduct a survey of the equipment used on your site and map their electrical consumption against the power your plant is using and is being charged for. We will then provide you a report of what your power factor is; and if it is low, how it can be corrected. For more information, call us at 1300 169 263. You can also drop us a line via email.
