Where the risk assessment calls for temporary bonding, the conductors are joined together and connected to earth where the work is being done, with leads rated for the fault current that could flow (flexible and at least 6 mm2 is recommended); bonding leads are always joined together and earthed before any attempt to attach them to de-energized parts, and suitable PPE is worn when attaching or removing them. Everyone working in the safe area must be told its limits and where adjacent exposed live parts are, and the area should be marked with barriers or signs. Work on de-energized equipment may only go ahead once it is isolated and all neighbouring exposed conductors in the work area are either de-energized and isolated or separated by barriers or a distance set by risk assessment (Figure 3.2); otherwise stop, or follow the live work rules.
