What is an overhead service main?


Overhead service main or overhead power is the cable that runs to your private home or commercial business from the network supply t point of supply. The service main can be attached to a private pole and then your home or it can also go directly to your home or business.

Depending on your needs, this service main can be single or three phase and range from 100 amps to 400amps.

Different sized service cables are used depending on your home or office requirements and over the years different types of service cable has been used.

What is an underground service main?


Underground service mains or underground power is the cable that runs to your home or business from the supply network but instead of being ariel, it is placed underground in conduit.

Just like overhead power, underground power can be single phase or 3 phase depending on your needs.

Underground power can be slightly more costly and sometimes access and ground conditions play a part in whether underground power is right for your area.

If you live on a property with lots of trees, going underground can be an option to avoid fallen powerlines in high winds and storms.
