Denmark Street in Diss was closed for an hour after a power cable fell.
Police were called to the scene at about 10.45am, closing off the road close to the mini roundabout.
A spokesperson for UK Power Networks told the Diss Express: “Repairs have been completed to an overhead power line which came down in Denmark Street, Diss.
“UK Power Networks engineers needed to isolate the electricity supply to one property between 11am and midday today in order to carry out the work.
“We apologise for any inconvenience caused.”
