Not just the problems associated with the above answers , But If there any underground hot wires where the insulation has cracked or peeled off anywhere it is buried underground , Electric current will leak into the ground and as long as the power is on , If it doesn't blow a fuse or trip the circuit breaker , Your electric bill will go up , Way up , Because the current leaking into the ground goes through the electric meter first , At the other end of the underground cable , Even if everything is turned off and the cable is still energized , Current continues to leak into the ground , Running the electric meter which raises your electric bill , Many people that install direct burial cable stretch it out , To get it as straight as possible to ensure that it will reach it's destination , What happens is when the ground gets warm in the summer , When the ground expands , It will stretch the cable even further which will cause it to break , When laying direct burial cable , You need to "Zig Zag" it in the trench a little to allow for expansion and contraction to prevent breakage
Once electricity meets a sufficient ground conducting element the breaker trips off and the flow of electricity ceases in less than the blink of an eye. The wire's insulation is designed to expand and contract within a given temperature range specified by national testing labs.
