Brenden Shaffer · Answer 1

Both technicians are correct

Explanation:

Insulated rubber gloves or lineman's gloves are a major requirement to ensure safety when working with high voltage parts of the hybrid electric vehicles because rubber is an insulator i. e. it does not allow direct contact of electricity with the body. These gloves are really important because these gloves can protect the technicians from electric shocks servicing the high voltage system on hybrid electric vehicles. It needs to be ensured that the gloves are of pure rubber and have no holes or cuts to ensure complete insulation. These gloves are also called class "0" gloves or gloves rated at 1000 V are used for this.

Similarly there are methods to shut off the high voltage to components and circuits in hybrid cars. These methods include but are not limited to:

• Turning the ignition off

• Disconnecting the 12-volt auxiliary battery

• Removing the main fuse, relay, or HV plug

So both the technicians are correct
