It is likely this street was named owing to its proximity to an electrical engineering works: Hugh J Scott Co. Ltd. called Volt Works in 1902 on the OSNI Historical Third Edition (1900 - 1907) map. It became Thrige-Scott and was then bought over by the electrical engineers ABB.
"...also application from Mr J. Scott to name a street on his property situate off Ravenhill Avenue, uan Street, and the Surveyor was instructed to request Messrs ... and Scott to submit other names for the respective streets. (21st June 1921)
"The Surveyor reported that Mr. Scott had suggested the name of Ampere Street for the new street off Ravenhill Avenue in lieu of Cuan Street, which had been disapproved at last meeting, and it was Resolved: That the name now submitted be approved of". (5th July 1921).
