A Queensland electrician whose greed and negligence caused the death of a young labourer has spent his first night behind bars after receiving a minimum two-year jail sentence.
Nathan Day was on Friday handed a head sentence of seven years after earlier pleading guilty to the February 2012 manslaughter of Jason Garrels.
The 31-year-old was also sentenced for perjury after lying to a 2015 coronial inquest about the electrical safety measures in place at the construction site where Mr Garrels was electrocuted.
A switchboard the 20-year-old was carrying contacted live wires at a site where 81 homes were being built at Clermont, west of Mackay.
In handing down Day's punishment, Justice Helen Bowskill found he had switched power off to two streets on which work was being done but not a third, where Mr Garrels was labouring.
Day had also not installed a safety switch, had incorrectly set up fuses and ran live wires across the ground in conduit instead of burying them
Mr Garrels was remembered as an easy-going larrikin by his parents, who gave powerful impact statements to the Brisbane Supreme Court.
"My life feels like a surreal hell I cannot wake up from," mother Lee Garrels wrote.
Day will first be eligible for parole in March 2020.
