    Type of DNO supply question

    I was installing a new control panel in a pumping station kiosk the other day. Sometimes I am required to `enter` the DNO supply to insert the earth cable on what is normally a TNCS system.

    I don’t normally get excited – but it’s a brushless motor: Makita Jigsaw

    I’ll be getting one before the month is out (when customers pay their bills!) hopefully then the “50% longer run time per battery charge” that Makita are claiming is true and my batteries last more than 20 mins lol. **link removed** Anyone got one? Any good?
