You'll be needing one when the manufacturers put in their instructions that terminal screws are to be torqued to a set limit
Told a story today of a Hager board fire, all parties arrived at the location where the fire occurred.
The Hager tech rep asked "can you show us how you tighten the terminals" sparks gets out a normal driver tightens the first terminal.
Hager hand over their instructions where it states the use of a torque driver is required & excuse themselves from the gathering stating the consumer unit has been incorrectly installed & any responsibility for the failure lies with the installing contractor.
Hence there may be a requirement in the future to show a torque drive on assessments, that info was from my assessor today.
Even states it on the Hager youtube advert
