Harry forgot that:

Padmount transformers can be dangerous if they are open or struck by a vehicle.

He should have remembered:

	You never touch one.
	Always tell an adult if the lock is broken or the door is open.
	If you see a vehicle accident involving a padmount transformer, call the electrical utility and 911.
	Stay back ten metres.

A transformer that has been enclosed in a protective metal housing and mounted on a concrete pad. It is used to reduce the line voltage to the 120 volt level that is used in your home.
