The electrical field is one that has seen a number of remarkable discoveries over the decades. One very important lesson has been the aspect of grounding of electrical currents. It’s true that we need electricity for almost everything in our daily lives and can’t even imagine a world without it. However, it continues to be one of the most dangerous elements on earth. If you haven’t already properly grounded your home’s electrical systems, you are taking a significant risk by not doing so.

Every electrical circuit has an active wire which supplies power; there is also a neutral wire which is responsible for carrying the power back. There is a third wire (grounding wire) that can be attached to the power outlets & the electrical appliances and devices; this wire is connected securely to the ground in your breaker box.

This third wire is the additional path that the electrical current can pass through to be safely returned to the ground, in case there is a short circuit; this prevents any harm being caused to anyone. In the event that a short circuit occurs, the current flows through into this grounding wire and it’s when you notice a tripped circuit breaker or a blown fuse in the electrical main board on your property. If this wire hadn’t been grounded, it would have resulted in a fatal shock.

This is one of the most important reasons to ground electrical currents. It’s the best way to protect your family members from electrical surges when they are operating any electrical appliances in the house. In case a lightning strike causes an electrical surge on your property it can result in extremely high electrical voltages in your system. When the wiring has the proper grounding, all the excess electricity gets diverted into the earth, rather than burning everything that’s connected to your electrical system.

When your installation is grounded, it becomes very easy for the power to get directed exactly to where you need it; this allows the electrical currents to efficiently & safely travel across your home’s electrical system.

A properly grounded system makes it much easier for the power to be distributed in the right amount to the right places. This plays a significant role in ensuring that there is no overload in the circuits. The earth becomes the common reference point for all the different sources of voltage in an electrical system.

One of the primary reasons why grounding is extremely effective in keeping you safe is because the earth is an excellent conductor, and electricity always takes the path that has the least resistance. When you ground your electrical system, you are giving it a path that it can easily take, rather than into you; this can potentially save your life.

If your home’s electrical system isn’t properly grounded, you are just risking the appliances and equipment that are connected to your system, being burnt beyond repair. If the situation gets out of control that can also result in a fire risking your property and causing physical injury, sometimes even death.

If you aren’t sure about whether your electrical system has the right grounding, its best to call in a reliable local electrician to get it checked thoroughly. We at AllRound Electrical will check the system carefully and check it for any other potential faults as well. For more information, contact our friendly team at this number – 1300 169 263.

LED sign lighting provides years of illumination and low energy costs. sign modules that consume 50mA of power each. Required materials differ depending on sign size, module size, length of wire between modules, current draw, and lumen output.

Materials:

1. First, measure your sign. Although we recommend spacing module rows 3 inches apart, it’s ultimately up to you. If you want a brighter sign, place them closer together and vice versa for a dimmer sign. With the recommended 3-inch spacing, a 4-foot square sign would need 150 modules (15 rows of 10). Again, the quantity of modules needed  is based on many factors and can differ.

These LED sign modules are available in custom lengths of up to 20 modules per strand. Order 60 feet (4 feet x 15 rows) of stranded modules, and cut the strand after every 10 modules. Each strand can be cut to make two rows.

2. Next you’ll need to order a power supply that’s rated for the combined wattage of all sign modules. To ensure that you don’t overwork the power supply, confirm that the total wattage of your modules is at least 20 percent less than the power supply’s rated wattage.

An easy way to calculate this is to multiply the total wattage of your combined lighting by 1.2. In the 4-foot sign diagram, there are 150 modules with a current draw of 50 milliamps (mA) each. Since current draw is given in milliamps, multiply that number by voltage and move the decimal 3 places to the left to get wattage. This module consumes 50 mA and has 12 VDC operation, so it consumes 0.6 watts (50 x 12 = 600). Next, multiply 0.6 by 150 to get a combined wattage of 90 and multiply that number by 1.2 (90 x 1.2 = 108) to determine which power supply you’ll need. Since the result was 108, you will need at least a 120-watt power supply.

3. Next on the list is wire to connect all your sign module stands to the power supply. For a 4-foot sign, you’ll need 4 feet of 18-gauge two-conductor wire to serve as your main line plus enough to cover the distance between your power supply and where it will be wired into an electrical system. You’ll also need dual-channel T-tap wire splice connectors for an easy connection to your main line.

Before you begin working on your sign, turn off power to the area.

4. If there isn’t one already, drill a hole in the back of your sign as an exit point for your wire.

5. Use a tape measure or ruler to plot your row spacing. Leave space on one side of the sign for your module-to-main-line connections. Mount the sign modules using their double-sided adhesive and/or screw holes.

6. Insert the end wires of each sign module row into the T-tap splice connector, and clamp the other end of the connector onto the main line. The splice connectors eliminate the need to strip wire insulation.

7. Use double-sided foam tape to secure each T-tap splice connector to the inside of your sign.

8. Reattach your sign’s front cover.

9. Connect the main line to your power supply, wire the supply into your electrical system, and restore power to the area.
