Then maybe 20-30 years ago people started getting concerned about aesthetics and those ugly poles and power lines, so newer developments started going with the more expensive buried power and utilities. One thing we don't have to worry with our overhead lines and transformers is having a ground or buried transformer getting invaded by ants and shorting out the system. That happens sometimes. Occasionally we will hear on the news about a whole block of houses in a buried power lines area that got a big power surge through the 120V lines frying everything plugged in inside the homes.

Our transformers for the underground utilities are pad-mount, above ground green metal boxes. They have two access panels, one for the HV feeders and lightning arrestor and one for the secondary connections.
