Power was cut to 93 properties as firefighters investigated smoke rising from a manhole cover.
A fire crew were called to Bromley Lane, Bromley, near Pensnett, shortly before 7am today.
Western Power Distribution cut the electric supply to properties in the wake out of the call out.
Posts on Facebook page "I'm from High Acres, Kingswinford, Wordsley and surrounding areas" said it looked like the "electrics under the footpath are on fire".
Another added: "It looked like it was going to explode."
Other residents said they had been left without power.
The fire was in the underground electrical link box, said West Midlands Fire Service.
A West Midlands Fire Service spokesman said its crew left the scene at around 7.41am in the care of Western Power, whose engineers were attempting repairs.
Western Power Distribution said engineers were able to make repairs and fully restore supplies by 1pm.
