Steel framed workshop.

Just a thought,but what type of structure,are these A frames?
If they are made up of bolted or riveted sections,you may find you are not bonding all parts,dependant on where you stick your eye terminal.

An assessment of the merits of your bonding,may be needed

Older lattice type steelwork,used in buildings,bridges,over-head cranes,etc is notorious for it's continuity mood-swings.

Bolted brand new A frames, yes they will give full continuity.

What do you mean an assesment of my bonding merits may be needed? If they are extraneous which they are then they need bonding, but my original thought was if you main bonded one wouldnt that be enough?

Im not bonding a bridge or a crane its a steel frames workshop!

Hi,your first line is the answer,then.

My reference to bridges and cranes,was in regard of the type of construction,of steel sections in older pre-fabs,Romney buildings,etc.

I have seen similar structures,with additional supplementary bonding,fitted correctly,frame to frame,stud welded eye terminals,no breaks... but varying or poor readings,as you test along and away,from the bonding.

So,in effect,bonded,but not effectively. It would be a situation such as this,that may require a bonding merit assessment

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

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

or 10.0mm bonding cable to my pacemaker?

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

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

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...

is that tested in the box, or on me yed?

I would do it on yer yed.
