Government regulations require the Men's Shed performs an electrical test & tag on all mains-powered devices twice annually. Most test devices cost arouns $1800 and it's hard for testers to cover their costs for less than $15 per item. Our shed gas 130 items, to test all of these each year would cost almost $4000.
We were lucky to get a testing device from a shed member for just $300. It costs another $400 to train an operator and $380 annually to calibrate the device so it's still legal.
So for an annual cost of just under $400 we can save $3500 by not getting an outsider to do the tests. Big win.
