[QUOTE="says-les, post: 537703, member: 15145"] We go to length by design to ensure shock protection. Zs must be measured and be below a certain figure. If the user is working at the end of a 30 Metre extension, he is risking a shock if a fault to earth occurs while using an earthed metal tool. The disconnection time will exceed 0.4 sec. No? I am assuming that Zs at the tool will exceed the max allowed value in the BBB. [/QUOTE]
