Hoping one of the experienced electrical guys can respond to this. Traditionally, I've worked in the IT environment, where from an electrical hazard perspective, I am considered an uneducated untrained person, and unless I stick a screwdriver into a power cord, its pretty impossible to come in contact with hazardous electrical energy. Now, I am having to provide support for equipment in control rooms that are AC powered, but terminated in terminal blocks. This does not provide as much protection as an AS3112 plug/socket or C13/C14 coupling. Grabbing the connector or a stray screwdriver could easily result in contact with 240v AC. I would expect a cover to some IP level to be required wherever the outer jacket of the power cable has been stripped back (ie you can see brown or blue cables). I would also expect an electrical hazard label to be placed on the cover, or maybe on the cabinet, or maybe on the facility door, depending on how granular the environment needs to be set. is there something official in aust standards, or state (wa) or federal requirements that say if/how terminal blocks should be covered and what warnings should be provided?
