You've been missing out

almost all jobs ive done in conduit, weve used distance saddles. saves you having to set your tube into gear

The old "hospital saddle" great stuff

 

[malcolmsanford]

In my 25 years of sparking, I have never done an install that relied on the conduit as an earth.

Was that a specification from another authority or regulatory body ?

Aren't hospital saddles far thicker than distance saddles...to allow for cleaning behind???? remember having this discussion with a storeman in the eighties!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

 

[malcolmsanford]

Now in all honesty Steve I never heard of distance saddles mate lol I only knew spacer or hospital saddles.

I just googled distance saddles and a page load of these came out ...................hospital saddles to me lol

 

[Bradzz]

Nah mate hospital saddles are wider to the wall and thiner to the conduit end.

i would've assumed most new work in steel is done with separate cpc's these days-it's considered good practice anyhow

same with SWA sub-mains -all 5-core probably these days

don't work in the UK but that's the way all jobs i work on are done


steel gives you great reading's and takes most of fault current anyway(about 90% with separate cpc)-but still

I did know Dave that some authorities did ask for seperate CPC's, espicially in corrosive atomspheres. I remember many years ago working in the goldstone factory and in certain areas there they insisted on class 4 conduit but seperate CPC run within the conduit.

But the BS 7671-2008 still recognises the use of conduit as a CPC and to be honest, unless it was a particular design like above I would still use it as a CPC.

Though i agree with you in the use of a separate CPCs in conduits, conduit installed correctly and professionally can and will give you a very good earth return. This was always proved by testing with a 25A ductor test. One of the last projects i was involved in, in the UK was a large shopping centre that totally relied on the steel conduit, throughout the whole building. Never saw a bad reading on any of the final tests i witnessed!!!

Distance is the correct name, they was used on hospitals all the time and that's how they got the name

[Knobhead]

MrEnigma, I wonder how many of our compatriates on the board would recognise a “Ductor”?
