Application
The Type SE, Style SEU service entrance cable is primarily employed for the conveyance of electrical power from the service drop to the meter base and from the meter base to the distribution panelboard. However, the cable may be utilised in all applications where Type SE cable is permitted. The SER may be deployed in wet or dry locations at temperatures not exceeding 90°C. The voltage rating is 600 volts.

How to use concentric cable
Proper use of split concentric cable requires following the following steps and precautions:
Inspection before installation: Before installation, check whether the cable is intact, confirm whether the insulation is intact, and rule out moisture, damage or other undesirable conditions.
Precautions during installation: When laying cables, avoid excessive stretching or twisting of the cables to ensure that the cables are not damaged. Use suitable brackets and fixtures as needed to ensure safe cable routing.
Connection method: According to the design requirements of the electrical system, correctly connect the phase wire, neutral wire and ground wire of the split concentric cable to ensure a firm and reliable connection.
Environmental adaptability: According to the environment in which the cable is used, select a cable type that meets the requirements. For example, outdoor laying requires waterproof and weather-resistant cables.
Follow safety standards: During installation and use, follow local safety standards and regulations to ensure the safety and reliability of the cable.
Involvement of professionals: For complex split concentric cable installations, it is recommended that professional electrical engineers or electricians carry out design and installation to ensure compliance with relevant safety and electrical requirements.
The correct use of split concentric cable requires comprehensive consideration of various factors during cable selection, installation and use to ensure the safe and reliable operation of the electrical system.
