| Electricity Meter Installation Electric meters are a great way to track the amount of electricity you use. They can also help you cut your power bills! They are typically a clear glass-encased metering device that resembles a large mason Jar. They have five dials and an enormous rotating meter that measures kilowatt hours. The Feeder Side The feeder side of an electricity meter installation is the most important to the homeowner since it connects to the overall electrical Installation Prices service. This area of the meter base is where the feed from the utility company gets connected to the meter and the wires connecting it to the remainder of your home's electrical system. It's also where you'll discover the most obvious wire connections: neutral, hot and ground. The best part is that the utility company usually provides the meter and wiring, but the responsibility of putting it all together is up to you. You'll need to put together the best meter base. The most important thing to do is figure out the meter's orientation (left or right hand front) and Electrical Installation prices then take a measurement of the length of each of the three wires you intend to connect to it. The best method to do this is to use a telescoping measuring tape Don't forget to put on gloves. The Load Side The load side of an installation electricity meter is where the electric feed leaves the meter, and is fed into the main service panel. The feed can come from a single breaker or several circuit breakers inside the main panel. The load connection is created at the two bottom load terminals of the meter's hot bus bars. However it is possible to do this using an interim disconnect (see Figure 3). The wiring from the service wires to meter must be in conduit and must be located in a place where it is not hindered by furniture or other obstructions. It should be at minimum two feet (2') from any exposed wiring on the side of the meter that is loaded and Electrical Installation Prices should be connected to the meter base with an opening cap on top of the conduit (see figure 16). If the wires are not in conduit, then they should be routed via a weatherproof conduit, or until LES allows a different method. The conduit should be accessible to Company representatives for meter reading and testing. The base of the meter must be secured to the block studs of concrete or brick. If the meter will be mounted on metal, vinyl or wood lap siding an underlying of 3/4" thick outdoor plywood must be used. It should be positioned level and plumb. It should also be set in a place in which the meter can be easily accessible by Company personnel for reading of the meter as well as testing and maintenance. The Grounding Wire Electricity meters come with the use of a grounding cable to protect the house from over-electricity. When an over-voltage or short circuit electricity is present and the grounding wire is damaged, it can help in safely removing the electricity from the house and keep it from flowing back to the mains. One way that the grounding wire is connected to the earth outside your home is to use copper water pipes or an 8-foot long ground rod. It can be connected to a copper waterpipe , or an 8-foot long ground rod is inserted into the soil. If the grounding wire isn't functioning correctly, excess power can escape through other channels and into your home. This can cause damage to appliances and electronics, or even the possibility of a house fire. It's important to understand what these issues are and what you can do to prevent them from happening. The prongs can be a good way to check if your outlets are grounded. Grounded outlets have three slots and ungrounded ones have two. The ground wire is connected to the d-shaped slot below the parallel slots. Electrical currents draw attention to the solid mass of earth beneath your feet since it has a negative electrical charge. Ground wires are designed to help these positive charges find a safe place to go , so that they don't get energized and cause a problem. If your electric meter was not installed or has been repaired recently, you should contact your utility provider. They'll be able verify that it was properly grounded. To ensure that it's operating properly an electrician with a license should examine the meter. If you are choosing an electrician to install your new meters, make sure you are aware of the rules and regulations your local utility provider has set. They're responsible for protecting your home from excessive voltages and keeping your family secure. They must connect the ground wire to base of the meter, and make sure that all metal casings that contain electrical installation contractor loads are bonded to system neutral. If the hot or neutral wires are energized, it could cause the breaker to trip. This is a potentially dangerous situation that could result in an electrical shock or death. The Meter Mechanism The Meter Mechanism is a crucial element of an electric meter installation. It is a way to determine the actual consumption of electricity. It is usually located on an electric shower installation near me pole or inside a box. The metering mechanism in an electric meter is typically a disc composed of aluminum that rotates in response to changes in the coil's magnetic fields caused by the voltage and the current flowing through it. It spins at a pace that is proportional to the amount of electricity it consumes. A spindle fitted with gears to it holds the length of a meter. The gears spin an electronic register that displays the energy consumed by series dials in kilowatt hours (kWh). An electricity meter is comprised of three main components comprised of the disc, disc's mechanism, and an LCD. The disc is the main component of the meter, as it determines the amount of power consumed and the total number of kWh. To obtain a precise reading, the meter has to be calibrated according to a standard. This procedure is typically carried out in a test laboratory. In this procedure, the meter's circuit is checked to ensure it's not over- or under-volting the wattage. Once the meter is properly calibrated, it may be put into a box. It is connected to the reference voltage, ground wire, and an earthing cable that connects from the meter box into a grounding rod buried under the ground. Sometimes, a meter might export power to the grid in addition to its consumption. In these cases, the meter may reverse its course during times when there is net export, and decrease the customer's total energy consumption. This results in the customer being credited for the energy that is pumped out of the meter into the grid, even if it is less than what's actually consumed at the meter. The technician must connect the line and load cables to the terminals of the neutral bus bar located in the middle of the meterbox to ensure that the meter runs correctly. These wires are typically marked with white tape to indicate them as neutral. After the wires are properly spliced they are then secured by being tightened. |
