How to use amp meter

During my first aid training we were taught that the electricity is not off until the fuses are in YOUR pocket. Don't trust even the "professionals" to say it's ok if you're the one going to be doing the actual dangerous bit!

see my earlier comments,   make sure you witness the fuses being removed from the correct location too

If you remember the old tube TVs, they had an EHT rail of 8000 - 12000 volts. To adjust the purity, we had to adjust some magnetic rings around the tube neck, quite close to the EHT rectifier. We often got a flashover, but the rule was, keep one hand in your pocket, so although it made you jump, it wasn't fatal.
