New Zealand mechanical protection ?

[martinh89]

This might come across as a stupid question but im only a trainee and still learning.

Do you need to mechanicly protect cable clipped direct in a commercial building but its protected by 30ma RCD, the cable is flex and the circuits that have been installed are fixed power outlets on 13a plug .

This isnt my installation , 2 electricians came into my work a few days ago and did a pretty shabby job.

mechanical protection would be required if there was a likelyhood of the cable being damaged by any sort of impact. shabby job is no excuse even if cable is clipped.

i doubt theyve used flex , are you sure its not fp200 or hi-tuff ? both of which have a hard rigid outer sheathing.
in what room has the wiring been installed ? nothing wrong in clipping direct per se , so long as its suitable for the environment.

no i actually asked the bloke installing it what type of cable it were , he just said flex. I then asked didnt it need to be mechanically protected and he said no its rcd protected.
Im only still learning but i always thought if something was clipped direct it needed some degree of protection, thats why i asked the question on here

Is it likely to be mechanically damaged, who designed the circuit if you have in house electricians?

hees talking throught his arse then. RCDs are not a substitute for mechanical protection and/or, poor design..

Yes deffinitely likely to be damaged , its been clipped to a table where people work. No my workplace doesnt have inhouse sparks.
my boss is aware im doing an electrical course outside of work and prior to the install he apporched me and asked for my opinion.
I told him id do a new circuit from d/b 20a radial circuit in swa cable. 4 double socket outlets in total and after my calculations the total design current were 16a

Sounds as rough as a badgers then. Pics would be nice . What is the environment ?

Sounds like you'd do a better job

ill get some pictures up monday night , and its poduction engineering enviroment , lots of hammering and cutting tools used

just to clarify, electrical work has been carried out in your workplace, which your boss has asked you about because he knows you are doing a course, and suspects that the work is substandard?

 

[martinh89]

no my boss isnt bothered as long as it works :/

Well he'll also be left accountable if problems arise. Test and inspect cert springs to mind.

but this part is true, yes?
