OK, I have worked in several small shops whilst training to be a manager (all owned by the same company, wont say which here!), and all have been recently refurbished (2-4 years ago). What surprises me about these shops though, is that none of the circuits are RCD protected. Not a single RCD to be seen anywhere within the installations. What are the regs concerning this?
Customers, as well as staff, can touch the metal bodies of the dairy chillers, metal electronic shutters, the photocopier, lights in the magazine racks. And in some of these shops, the chillers are in a shocking state, very old (10-15 years old), with massive starting currents, and i wouldnt be surprised if they were dumping huge amounts of current to earth.
Also, in the shop i'm at now, the shopfloor lights are controlled by a timer (so i've been told, and there are no light switches for the shopfloor anywhere). The only contactors i can see are labelled "beer/pop chillers" and "outside lights", And there are 2 timers to match, all attached to the sides of the DB. The shop floor lights take up 4 circuits on the DB, all on a same phase. What are the chances these are actually connected to the outside light contactor? Is this even possible with 4 circuits on a single contactor? Might try and get some pics so you can see what im on about here!
By the front door, there is a keyswitch under a break glass point for the fire alarm, connected by conduit to the ceiling. Any suggestions what this is for? Nobody knows!
All comments welcomed! Im just curious about this sort of thing. If the management thing doesnt work out, ill be training as a spark!
