Wow, good to know, I started my career as an Electrical Fitter 330kV/110kV Substation Distribution (Instalations/Maintenance) for 12years before moving into Design Draughting in the same field. Until this day, I will never get used to battery operated tools (yeah I'm old school). My 240V hand drill still scares my SIL, nearly broke his wrist drilling a 3/8 erm 10mm masonry drill bit.
