Electricity Meter Installation
An electric meter is an excellent method of keeping track your consumption of electricity. They can also reduce the cost of your power.
They are typically transparent metering devices encased in glass that resembles an oversize mason jar. They come with five dials and a large , rotating wheel which is used to measure Kilowatt-hours of electricity.
The Feeder Side
The most crucial part of an electricity meter installation for homeowners is the feeder side. This is because it connects to the entire electrical service. This is the place where the utility company's feed connects to the meter and the wires connect to the electrical system in your home. In this area, you'll find the most obvious wire connections: neutral, hot, and ground. The best thing is that the utility company will usually provide the meter as well as the necessary wiring. However, you are accountable for putting it all together.
To construct the best base for your meter you'll need a few of the mentioned items, as well as an ample amount of anti-corrosion material to shield your wires from the elements. First, determine the orientation of the meter (left or right-hand front) and then take a measurement of the lengths of the three wires that you plan to connect to it. A measuring tape with telescoping capabilities is the best tool to accomplish this. Make sure to wear gloves.
The Load Side
The load side of an electricity meter installation is where the incoming electrical feed leaves the meter and enters the main service panel. This feed can be from a single or multiple circuit breakers within the main panel. The connection to the load is located at the two lower load terminals on the meter's hot buses bars. However, this can be done with an interim disconnect (see Figure 3).
The wiring from the service wires to the meter should be in conduit and be located in a position that is not blocked by furniture or other obstructions. It should be at least 2' from any exposed wiring on load side of the meter.
If the wires aren't in conduit, they must be routed in a weatherproof conduit unless LES approves a different method. The conduit should be in a position where it is unobstructed by anything and is easily accessible by Company representatives for meter reading or testing.
The meter base must be securely fixed to the block studs of concrete or brick. A backing of 3/4-inch thick outdoor plywood is required for meter bases that be mounted on vinyl, metal, or wood lap siding. It should be positioned on a level surface and plumb. It should be in a place where it is easy for Company representatives to be able to read, test and maintain the meters.
Grounding Wire
A grounding cable is found in electricity meters to shield your home from excess electricity. If a short circuit or excess electricity is present in the home, the grounding wire could help to safely discharge the electricity from the home and stop it from returning to the mains.
The grounding wire connects to the earth outside your home in one of two ways. It can either be connected to the copper water pipe or an 8-foot long ground rod driven into the soil.
When the grounding wire isn't grounded, excessive electrical current can escape through other channels into your home and cause damage to appliances and electronics , or an eventual house fire. It is important to know what these issues are and how they can be dealt with to prevent them from happening.
The prongs are an excellent method to determine if your outlets have been grounded. Outlets that are grounded have three slots whereas ungrounded outlets have just two slots. The ground wire is connected to the d-shaped slot below the parallel slots.
Electrical currents draw attention to the solid mass of the earth beneath your feet since it has negative electrical charges. Ground wires are designed to allow these positive charges to be able to locate a safe spot so they don't get energized and cause problems.
If your electric meter was not installed or has been repaired after a while it is recommended that you contact your utility provider. They'll be able verify that it is properly grounded. To ensure that it's functioning properly, a licensed electrician must examine the meter.
When selecting an electrician to install your new meters, be aware of the rules and regulations that your local utility company has set. They're responsible for securing your home from over-voltages and keeping your family secure.
In addition to connecting the ground wire to the base of the meter, electricity meter installation they must also make sure that all metal casings for electrical loads are bonded to system neutral. If there's an electrical issue with the neutral or electricity meter installation hot wires, they can become active and contact the metal casings and trigger the breakers. This is a dangerous scenario that could cause an electrical shock, or even death.
The Meter Mechanism
The Meter Mechanism is the component of an electricity meter installation that makes the actual measurement. It is located on a utility pole inside a meter box or in the premises next to the distribution unit or the consumer unit. board.
The metering mechanism of an electric meter is usually an aluminum disc that spins in response to changes in the coil's magnetic fields caused by current and voltage. It spins at a rate that is proportional to the amount electric power it uses.
A spindle with gears attached to it supports an elongated disc of about a meter. The gears spin and display the energy consumed by series dial in kilowatts (kWh).
An electricity meter consists of three major parts which are the disc, the disc's mechanism. A display is also included. The most important part of an electricity meter is the disc. It determines how much electricity was used and how many kWh were used.
To obtain a precise reading, the meter must be calibrated to a specific standard. This procedure is typically carried out in a test laboratory. During this process the circuit of the meter is checked to ensure that it isn't over or under-volting the wattage.
Once the meter is calibrated properly, it can be put into a box. It is connected to the reference voltage grounded wire, as well as a grounding wire that runs from the meter box to a grounding rod buried under the ground.
In some cases the meter could export energy to the grid in addition to its consumption. In these scenarios the meter will be running in reverse during periods of net export and decrease the customer's total recorded energy usage. This allows the customer to be reimbursed for any energy that flows from the grid to the meter even if this is less than the actual consumption at the meter.
The technician must connect the load cable and line to the terminals at the neutral busbar in the center of the meter box to ensure that the meter is running properly. These wires are typically marked with white tape to indicate them as neutral. After the wires are properly spliced, they are then tightened to ensure they are secure.
