How to protect the secondary distribution box during construction

Laterals can be directly connected to main trunks, but are more commonly protected by protective devices such as fuses, re-closers, or automatic sectionalizers. Overhead laterals use pole-mounted distribution transformers to serve customers and underground laterals use pad mount. Lateral taps off of the main trunk are used to cover most of a feeder's service territory. These taps are typically single phase, but may also be two phases or three phases. The design of the high-voltage substation must include consideration for the safe operation and maintenance of the secondary equipment. The substation secondary systems are those systems which provide the functionality necessary to ensure safety of personnel engaged in operation of the substation. This Code of Practice should be titled 'Code of Practice for the Electricity (Wiring) Regulations' hereinafter referred as the 'CoP'. This explanation aims to clarify the roles and functions of primary, secondary, and tertiary distribution boxes, enhancing.
