Swapping PAT Tested Cables and Equipment

Hello,

Currently working as a Junior Engineer at a company and have been tasked on PAT testing all sorts of electrical equipment. 

In my office it is believed that equipment can only be used if tested together. For example, you cannot use any power lead, even if separately tested, to power a computer unless it has been PAT tested with the computer together.

Is this true, or are we able to combine two separately tested pieces of equipment, and where would this be written in the PAT guidelines (or the 5th Edition IET code of practice)

Thank you

  • If it's any help, when my employer PAT tests any equipment with detachable cables, they put stickers on both the cable and the equipment.  Then us engineers can mix and match appliances and cables to our hearts' content until the next PAT testing session.

  • The whole point of standard removable cables is that they are interchangeable. The alternative is a fixed lead.

    We do have 2 groups of IEC leads, as some are fitted with 13 and others with 5A fuses and are marked up accordingly - but we have a building full of engineering types.

    Note that there is no legal compulsion to PAT at all, but only to have a system that ensures safety - a PAT regime is only one way to do this.

    This peculiarity may have more to do with insurance or contractual arrangements, than engineering sense.
