Electricity Meter Installation
An electric meter is a great method of keeping track the amount of electricity you use. They can also help reduce your electricity bills. They are typically a clear glass-encased metering device that resembles a large mason jar. They contain five dials and a large rotating wheel which is used to measure the kilowatt-hours of power. The Feeder Side The most crucial part of the installation of an electricity meter for homeowners is the feeder. This is because it is connected to the entire electrical service. This area of the meter base is where the feed from the utility company gets connected to the meter as well as the wires that connect to the rest of your home's electrical system. This is where you'll find your most obvious wire connections: hot, neutral and ground. The best thing is that the utility company will typically provide the meter as well as the necessary wiring. However, you are the one who installs electric meters puts it all together. To assemble the top notch base for your meter you'll need several of the previously mentioned items, along with a hefty helping of anti-corrosion compound to shield your wires from the elements. First consider the orientation of the meter (left or right-hand front) and then measure the lengths of the three wires you plan to connect to it. The best way to do this is to make use of a telescoping measuring tape Don't forget to wear a pair of gloves. The Load Side The load side of an installation electricity meter is where the incoming electric feed leaves the meter, and enters into the main service panel. The feed can come from one breaker or several circuit breakers located in the main panel. The load connection is located at the two lower load terminals located on the hot buses bars. However, this can be done using an interim disconnect (see Figure 3). The wiring from the service wires to the meter should be in conduit and must be in a location in a place that isn't blocked by furniture or other obstructions. It should be at least 2' away from any exposed wiring on load side of meter. Unless LES is in agreement with a different method wires shouldn't be run in conduit. The conduit should be accessible to Company representatives to read meters and test. The base of the meter needs to be securely attached to the brick's studs or concrete block or the equivalent. If the meter is to be hung on metal, vinyl or wood lap siding, a backing of 3/4 inch thick outdoor plywood should be utilized. It should be positioned level and plumb. It should be placed in an area where it is easy for Company employees to read, test and maintain the meters. Grounding Wire Electricity meters come with a grounding wire to protect the home from the effects of excess electricity. Grounding wires are used to remove power from the home in the case of an overload or short circuit. electric current. One method by which the grounding wire is connected to the earth outside your home is to use a copper water pipe or an 8-foot long ground rod. It can be connected to an copper water pipe or an 8-foot long ground rod driven into the soil. When the grounding wire isn't properly grounded, excessive electrical current can escape through other pathways into your home, causing damage to appliances and electronics , or the possibility of a house fire. It is essential to be aware of the root of the problem to avoid them. A simple way to determine if your outlets are grounded or not is by looking at the prongs. Ground outlets have three slots whereas ungrounded outlets have only two slots. The d-shaped slot directly below the parallel slots is that is connected to your ground wire. Currents of electricity are attracted by the solid mass of earth beneath your feet since it has an electrical charge that is negative. Ground wires are designed to let these positive charges be able to locate a safe spot so they don't become energized and cause trouble. If your electric meter was not installed or repaired after a while you should get in touch with your utility company. They'll be able verify that it is properly grounded. If it's not properly grounded, you must have a licensed electrician inspect the device and verify that it's operating properly. If you are choosing an electrician to install outdoor socket your new meters, be aware of the rules and regulations that your local utility company has set. They are responsible for protecting your home and Who Installs Electric Meters keeping your family safe. They must connect the ground wire to base of meter and ensure the metal casings with electrical installations testing loads are bonded with system neutral. If the hot or neutral wires get energized, they could trigger the breaker. This could result in an electrical installation prices shock, or even death. The Meter Mechanism The Meter Mechanism is the part of an electricity meter system that makes the actual measurement. It is located on a utility pole in a meter box, or inside the building adjacent to the consumer unit or distribution board. The metering mechanism of an electric meter is typically a disc made of aluminum. It rotates in response to changes in a coil's magnetic fields due to the current and voltage across it. It spins at a rate that is proportional to the amount of electricity it consumes. A meter disc is typically supported by a spindle which is fitted with gears. The gears spin into a register that displays the energy consumed on a series of dials in kilowatt-hours (kWh). An electricity meter has three major components: the disc, the mechanism that drives the disc, as well as an LCD. The most important component of an electricity meter is the disc. It determines how much electricity was used and how many kWh were consumed. The meter needs to be calibrated according to an established standard to get an accurate reading. This is typically done in a laboratory. During this procedure the meter will be tested to ensure that it is not over or undershooting the power or current of its circuit. Once the meter has been calibrated, it can be installed in a meter box. It is also connected to a reference voltage as well as a ground wire, as well as a grounding wire that leads from the box for the meter to a grounded rod buried in the ground. In some cases meters may export energy to the grid in addition to its consumption. In these instances, the meter may reverse itself during times that there is net export, and reduce the total energy consumption. This results in the customer being credited for the energy that flows from the meter to the grid, even if it is less than what's actually consumed by the meter. To ensure that the meter runs properly, Who installs electric Meters the technician must connect the line and load wires to terminals on the neutral bus bar located in the middle of the meter box. These wires are usually marked with white tape to indicate that they are neutral. After the wires are properly spliced, they are secured by being tightened. |
