If it's not been designed and just guest. Then you need to check the voltage drop on the cable . You will need various information to work this out including, max demand ,method of installation and length of run
As above . 60947-3 are just switches so do not protect from fault current. You need to know the manufacturer and make of the 60947-2 mccbs . Then go on the manufacturers web site . Where some have tables showing you the max Zs and other tech data
Working at a clinic the other day all the usual Covid saftey signs. Then found these on most of the chairs. I not sure what training I need to sit down !!!!
You make a good point and thanks this is good conversation, and so just to confirm an installation that was installed correct at the time of the 16th addition , could now be given an unsatisfactory report due to a code 2 such as cable not supported from premature collapse....
Yes I agree with this and yes the same danger applies. So really if my opinion is that an observation is a code 2 then I should code 2 it regardless of its age, My thought process was using the the seat belt analogy , you can drive a car without seat belts if was built before a certain...
Ok my reasoning is this.
If the electrical installation was installed after a regulation that was brought in as an improvement to safety, that regulation was not adhered to and I feel the regulation does prevent a potential danger then I would code 2 it. So my coding is based more to do with a...
Code 3 for cables buried less than 50mm in the wall . But if was design to the 17th addition or newer then I would and have given this observation a code 2
Yes I have got one of them. Had it for a though years now the only problem I find is the leads seam to ware out giving higher and higher reading . Its ok for continuity testing as you can null the meter but the zs reading always seem to be on the high side. Also there doesn't seam be a shoulder...
I think they where round to help with design. You would turn the lid to select how many entry holes you required. I did have to use one the other day as the wholesaler did not have any hager Ashley MF in stock but plenty of the 30 amp ones
Yes it's much better now thanks. I dont use any add blockers and I normally view the forum on my phone. I just see one add per page like the attached picture . Which is not a problem at all ?
All cables have to be the tri ratted type .not solid cores . As for surface conduit. Dont know of a reg to say you can't do this .It may be possible due to hygiene so surfaces can be cleaned down
That's the problem with all electrical reports and certs, they are not easy for the layman to understand .all they know it has to say satisfactory on it. We could do with an official document in plain English that explains what paper work required for these scenarios. Then we can pass this to...
We get this a lot . I try and explain that the . original EICR cover the whole installation stating what is correct and well as what is wrong. The EIC and or minor works states that the observations( the wrong bits) have now been corrected . So now you have all paper work to confirm that the...
