Hi everyone, this is my first post , after spending 8 hours on line and no success ,being an M&E Manager electrically biased, I check for conformity on twelve domestic construction sites, one in particular has a design and build electrical contractor, my issue is in the electrical intake room in the basement of a new build 5 storey apartments, the tray and trunking is installed to a good standard however all the conduit from a stop end box on the trunking is in white plastic, at least 60 lengths serving both high level lights, sockets and life safety systems, can someone please tell me is their is a BS or regulation which opposes this install, also where do the fire regulations sit with this.
Thank you for the quick response, much appreciated, the main concern I have as well as a few Electrical Contract Managers and Designers is that galv metal conduit has always been used in Electrical intake rooms, Plantrooms and external this has been to norm, however, I cannot find anything that says you should, the electrical sub-contractor in my mind are cutting cost , the questions with answers I require to bring to the table are:
1: does the plastic meet the requirement of IP protection for this area which includes all joints and boxes that are glued on.
2: does the fact that due to the glue the conduit or boxes are not interchangeable.
3: is there a specific fire rating for conduit in these areas.
4: the conduit will also carry circuits for fire alarms within the framework.
In a nut shell I am not content with install all the trunking is IP4 rated and fitting a plastic conduit via a 20mm bush and lock ring would this also compromise the IP rating of the trunking.
