Application
Concentric cables are employed as an electric service entrance from the power distribution network until the meter panel, particularly in instances where the objective is to prevent "black" losses or electric power robbery. Additionally, they are utilized as feeder cables from the meter panel until the panel or general distribution panel, in accordance with the specifications outlined in the National Electrical Code. This type of conductor is suitable for use in both dry and wet environments, including direct burial and outdoor applications. It can operate at temperatures up to 90°C and is rated for a service voltage of 600V.

You must to know when you use SER Cable
American SER cable is a multi-core cable that is commonly utilised in distributed power systems within residential and commercial buildings. Typically, the cable comprises two or three mutually insulated wires encased in a PVC sheath. This type of cable is frequently utilised in distributed power systems within indoor environments, for instance to facilitate the interconnection of power distribution panels, lighting fixtures, sockets, and so forth.
It is of the utmost importance to adhere to the following guidelines when utilising American SER cable in an appropriate manner:
The following specifications must be adhered to during the installation process: It is essential to ensure that the installation is carried out correctly, including the wiring, connections and fixings, in accordance with the requirements set out in the American Electrical Installation Code.
The following section outlines the circumstances in which this particular cable is applicable. SER cables are typically deployed in indoor settings and must be safeguarded from moisture, heat, and mechanical stress.
A reliable connection is essential. It is imperative that the cable connection is secure and reliable in order to prevent issues such as poor contact or an open circuit.
Load matching: It is advisable to ensure that the load is reasonably matched in accordance with the rated current and voltage of the cable, in order to avoid the potential for overload.
It is recommended that a regular inspection be conducted. It is imperative to conduct regular inspections of cables to ascertain that their insulation performance and connection status are in optimal condition. This allows for any potential issues to be promptly identified and addressed, ensuring the continued reliability and safety of the cables in use.
In general, the appropriate utilisation of American SER cables necessitates adherence to pertinent installation specifications and standards, thus ensuring safe and reliable usage. In the event of uncertainty regarding the correct utilisation of the aforementioned apparatus, it is advised to seek the expertise of a duly qualified electrical engineer or installer.
