Steel framed workshop.

bigspark17 · Feb 2, 2018

hi have a large workshop to price, standard stuff, but i noticed that the steels 4 of which are not bolted together so in a sense offer 4 earth fault paths, i would plan to export suitable earth/cpc conductor from house to bond the frame but should i bond each steel back to consumer unit(in workshop) or link them together or just bond 1.?
Usually in buildings like this i see that steels are connected together with other steels but on this occasion its timber between.
If i havent explained well i appoligise, but intrested to hear thoughts.

or 10.0mm bonding cable to my pacemaker?

As long as it's less than 3 meters long...

Yes well bonding each frame back to EMT will be the answer it just seems overkill as the frames will be giving very similar earth path readings

But that is the whole point, if each of the frames are a separate steel structure in contact with the ground each will introduce a separate earth potential

i just got back from specsavers, got new glasses, steel frames. should i use 6.0mm or 10.0mm bonding cable to my pacemaker?

Now,you,more than anybody,knows that the correct thing to do,is to find out if those frames are required to be bonded,or just a pair of spectacles.....get your IR tester,and...
