Electricity Meter Installation
Electric meters are a great tool to keep track of your usage of electricity. They can also help reduce your electricity bills.
They are usually transparent metering devices encased in glass that resembles an oversize mason jar. They come with five dials and a large rotating meter that can measure kilowatts of electricity.
The Feeder Side
The feeder part of an electricity meter installation is the most important to the homeowner because it is connected to the overall electrical installations service. The meter's base is where the power from the utility company is attached to the meter itself as well as the wires that connect to the other electrical components of your home's system. It is here that you will find the most obvious wire connections: neutral, hot, and ground. The best part is that the utility company will usually provide the meter and wiring. However, you're responsible for putting it all together.
For assembling the top of the line base for your meter, you'll require some of the above items as well as an abundance of anti-corrosion material to shield your wires from damage by the elements. First decide on the orientation of the meter (left or right-hand front), and then measure the lengths of the three wires will be connected to it. The best method to do this is to use a telescoping measuring tape make sure to wear gloves.
The Load Side
The load side of an electricity meter installation is where the electrical feed leaves the meter and enters the main service panel. The feed can come from one breaker or a number of circuit breakers within the main panel. The connection to the load is made at the two lowest load terminals of the meter's hot buses bars. However it is possible to do this using an interim disconnect (see Figure 3 phase meter installation (Kmgosi.Co.kr)).
The wiring connecting the service wires to meter must be in conduit and be in a location that is not blocked by furniture or other obstructions. It should be at minimum two feet (2') from any exposed wiring on the load side of the meter and 3 Phase Meter Installation should be connected to the base of the meter with an opening cap on top of the conduit (see figure 16).
Unless LES approves a better method, wires should not be run through conduit. The conduit should be accessible to Company representatives to conduct meter readings and tests.
The base of the meter must be secured to brick or concrete block studs. If the meter will be hung on vinyl, metal or wood lap siding, an underlying of 3/4" thick outdoor plywood must be used. It should be placed level and straight. It should be in an area that is easy for Company employees to read, test and maintain the meters.
Grounding Wire
Electricity meters come with the use of a grounding cable to protect your home from excessive electricity. When a short circuit or excess electricity occurs and the grounding wire is damaged, it can help to safely discharge the electricity from the home and prevent it from flowing back to the mains.
The grounding wire connects to the earth outside your home in one of two ways. It can either be connected to a copper water pipe or an 8-foot long ground rod that is driven into the soil.
When the grounding wire isn't grounded, excess electrical energy can escape through other routes into your home which can cause damage to electronic equipment and appliances, or even a potential house fire. It's important to understand what these issues are and how they can be dealt with to avoid them.
The prongs are a great way to check if your outlets are grounded. The outlets that are grounded have three slots and ungrounded ones have two. The ground wire is the one that is connected to the d-shaped slot underneath the parallel slots.
Because the earth beneath your feet is negative charges which is why domestic electrical installation currents are drawn to it. A ground wire is designed to help these positive charges find a safe spot to go , so that they don't get energized and cause a issue.
If you don't have an electric meter installed or it has been a while since the meter was repaired or replaced or repaired, you should call your utility provider to find out if it has been properly grounded. To ensure that it's functioning properly an electrician licensed by the state should inspect the meters.
If you're choosing an electrician to install your new meter remember that they must follow the rules and regulations established by your local utility company. They are accountable for protecting your home and keeping your family secure.
They must connect the ground wire to the base of the meter, and make sure that the metal casings with electrical installation and maintenance loads are connected to system neutral. If the hot or neutral wires become energized, it could cause the breaker to trip. This is a dangerous situation that could cause an electrical shock, or even death.
The Meter Mechanism
The Meter Mechanism is an important part of an electric meter installation. It is a way to determine the actual electricity consumption. It is usually located on an electric pole or inside the form of a box.
The metering mechanism in an electric meter is typically a disc made of aluminum. It turns in response to changes in a coil's magnetic field caused by the current and voltage across it. It spins at a pace proportional to the amount of electricity consumed.
A spindle with gears attached to it holds the length of a meter. The gears turn into a register that displays the energy consumed on a series of dials in kilowatt-hours (kWh).
An electricity meter has three primary components that include the disc, the mechanism for the disc, and finally, a display. The most important element of an electricity meter is the disc. It determines how much power was consumed and how many kWh were used.
The meter needs to be calibrated to an established standard to get an accurate reading. This is usually done in a lab. In this procedure, the meter's circuit is checked to ensure it's not over- or under-volting the power level.
Once the meter is properly calibrated, it may be placed in a 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 meter box to a grounding rod, which is then buried in the ground.
Sometimes, a meter may export energy to the grid and its consumption. In these scenarios, the meter will run in reverse during periods of net export and decrease the total energy usage. This will result in the customer getting credit for the energy that is pumped through the meter and into the grid, even if it is less than what's actually consumed by the meter.
The technician must connect the load cable and line to the terminals of the neutral bus bar located in the center of the meter box in order to ensure that the meter runs correctly. The wires are usually marked with white tape in order to identify them as neutral. Once the wires are correctly spliced, they are then tightened to ensure they are secure.
