1. Do I need a professional electrician to install the EV Charger?

In many situations, local electrical codes will require a licensed electrician to install the EV Charger. If this requirement does not apply to your situation and you are comfortable working with 240V electrical systems, a self-installation is possible. More information.

2. Does Emporia Energy provide a list of qualified installers/electricians?

In select areas of the US, you can purchase an Emporia EV Charger along with professional installation from one of our partner electricians. To check availability in your area, please visit: install.emporiaenergy.com.

3. What about ground fault protection?

The EV Charger includes built-in ground fault protection. Therefore, we highly recommend not installing the charger on a GFCI breaker as this can cause nuisance tripping. For more information on GFCI protections and installing the charger on GFCI breakers, refer to our detailed article. You can also find technical specifications on the protections provided on the device technical specifications PDF - found online here or via the file download located at the bottom of this article.

4. What wire diameter (AWG) should be used for power supply?

We recommend using 6 AWG copper wire rated for 90° C to allow the charger to operate at its full 48 amps. Please consult with a licensed electrician for the best power supply solution for your specific situation. More information.

5. Is the EV Charger suitable for outdoor installations?

The EV Charger housing is classified as a Type 4 NEMA enclosure, making it suitable for both indoor and outdoor use. It should function properly in all but the most extreme outdoor conditions. More information.

6. How is the NEMA outlet aligned?

The NEMA plug that comes with the EV Charger is 22 inches long and flexible enough to fit any orientation of an existing NEMA outlet. In the default installation with the NEMA plug hanging down from the EV Charger, the ground pin is at the bottom.

7. What is the size of the cable knockouts on the EV Charger?

The charger casing has a 1 1/4 inch diameter knockout. The included conduit fitting is 1 inch in diameter.

8. Is a neutral line required?

No, the EV Charger only requires two live lines and a ground/earth connection.

9. Can I install the NEMA plug with the ground pin facing up?

Yes, you can install the NEMA plug upside down. Ensure the charger is close enough to the outlet so there is enough slack to make the turn with the NEMA plug without straining the cable.

10. Are higher amperage breakers acceptable?

Yes, you can use any breaker size as needed. However, lower-rated breakers will reduce your available charge rate.

11. Should I use stranded or solid wire?

We recommend using solid core wire. However, a licensed electrician can confirm whether stranded wire will work for your particular situation.

12. Can the EV Charger work on a single-phase 240V line?

No, the charger requires a single-split phase (two lines) at 120V (line to neutral) with a 180° phase offset to operate correctly.

13. Are different length charging cables available?

Currently, we only offer a 24-foot charge cable with all EV Charger models.

Essentials Of Electrical Distribution System We Should Know

How does electricity reach our homes? This question isn&#;t just for the schoolers but do we know how electricity is transmitted from the power station to our kitchen? Are we aware of the electrical distribution system that carries this electricity?

Subsequently, this won&#;t be a head-scratcher because we will make it simpler for you right here.

Purpose Of Electrical Distribution System

Electrical Distribution System are an indispensable part of the electrical power system. The primary purpose of an electricity distribution system is to meet the customers&#; demands for energy after receiving the bulk electrical energy from transmission or substation.

Electric power distribution to the place of use is the final stage in the delivery of electric power to individual consumers. Depending on the geographical location, the distribution network can be in the form of overhead lines or underground cables.

Protection, control and monitoring equipment are provided to enable effective operation of the distribution network. Mostly LV or HV distribution lines consist of different types of structures (poles or towers of Wood, Concrete, Steel) used for supporting the overhead lines.

How Is Electricity Transmitted

Let us first look into the very basics of electricity generation. Electricity is generated at the power station, and then the current is fed to the transformers for increasing the voltage. Usually, this is done so to push the power over long distances.

Through transmission lines, it reaches the substation, where the voltage is lowered. It is then sent on lower power lines. It then travels through the distribution lines connecting the nearest poles to your homes.

From poles, the wires connect the service panels and meter in your homes to deliver the required electricity.

Distribution System And Stages

The distribution system consists of five main stages.

1- Distribution Substation

Here the high voltage from the transmission lines is lowered by the transformers. The voltage value depends upon geography and consumer usage.

2 &#; Distribution Feeders

The substation&#;s lowered voltage is sent to the distribution transformer via distribution feeders that are designed as per their current carrying capacity.

3 &#; Distribution Transformer

Distribution transformer or service transformer further lowers the voltage to utilisation voltage for household and commercial usage.

4 &#; Distributor Conductor

The distributor conductor carries the output from the distributor transformer. Tappings are derived from the conductor to transmit the power to the end consumer. Due to these tappings, the current and voltage in the conductor vary. This factor is taken into account while designing the conductors.

5 &#; Service Mains

The cable connects the distribution conductor to the nearest pole to the consumer end.

The Transmission Tower

The transmission towers carrying the high voltage power lines are also an essential part of the electrical distribution system. The giant towers carry these lines over myriad geographies.

They are supported by stay wire and its accessories. Stay wires are the twisted strands of galvanised steel wires that provide horizontal support to the tower.

Classification Of Distribution System

It is classified into three types. The first is according to the nature of current that includes DC and AC distribution system.

The next is based on construction type, that is, overhead or underground distribution system.

And the last is classified on the connection, including radial, ring-main, and interconnected systems.

Conclusion

As much as the process is essential, so are the essential parts required at every stage. Further, this can range from the cross arms and stay wire accessories to insulator fittings, ground wire accessories, and substation fittings.

The manufacturing and fabrication of accessories play a vital role in the distribution system&#;s overall quality.
