Hi i have built a standalone water rig for a college project. The rig is powered from a nearby socket and contains copperpiping and is built from unistrut. My question is what bonding would this rig require.
In the main the earth provided from the plug is enough. However you do need to check this is connected. The normal method would be to use a PAT testing machine which passes a 25 amp current through the earth path to check there are no bad connections. The rig will be registered as an item on the appliance list and there will be a record of it being tested. Likely also a sticker to say it has been tested.
