There are two popular variations of service entrance cable that we carry at Nassau Electrical â SER and SEU. SE service entrance cable has various uses, but can most often be found being used to convey power from the service drop to the meter base and from the meter base to the distribution panelboard. Beyond this, SER and SEU cable can be used in all applications where SE cable is permitted. If a temperature does not exceed 90 degrees C, SER can be used in dry or wet locations. The voltage rating of SER and SEU cable is 600 volts.
