yeah i just dont trust it, i like to see a nice big seperate earth. its only gonna be 10-15m run at the very most, there is a water supply coming into the unit so im gonna stick a bond on that as well. as well as a supp bond to me cable tray? gonna do some reading tongight on rcd's in commercials or is it simply gonna be rcbo's on everything as there will be no cables below 50mm etc?
with regards tray ,the question is ;is it an exposed conductive part ?
this answer is the regs regard it so .first look up exposed conductive part then look up electrical equipment in the definitions
klik assemblies make life easier for maintenance ,lamp replacement luminaire replacement ,testing ....if they are drawing a lot of current consider a plug and socket arrangement
oh we love these "discussions"
extraneous conductive parts are liable to introduce a potential from outside the equipotential zone and need equipotential bonding not supplementry bonding
with regards tray ,i'm just quoting definitions, bond /dont bond the choice is yours
without getting tied in regulation knots ,your talking about bonding in addition to the main within a special installation,hmmmm Wayne old chap, so why do we supp bond extraneous in bathrooms then?
or did before the 17th
someone more used to shopfitting desgn(tony?)can advise you best thereahh i see, the light fittings arnt on site yet, but like you say therll be a plug in the actual fitting coming from the klickety klix so thats ok then. in your opinion would it be beneficial having the main part of the shop on seperate mcbs for the lighting, like i said above? ive got enough spare ways in the board so...
ps on the e/lighting side i think im just gonna do a couple of circtuit straight from the board with key switches positioned appropriately.

without getting tied in regulation knots ,your talking about bonding in addition to the main within a special installation,
tray is still defined as exposed
someone more used to shopfitting desgn(tony?)can advise you best there
yes!!!! (sorry for the !! apparently i cant just put yes )!is it Wayne, think about it, why is tray exposed?
does it meet the defenition
im talking definitions see post 26
part of the definition of electrical equipment states ; wiring systems, accessories, appliances and luminaires.
exposed conductive parts are connected using just a protective conductor(411.3.1.1)
if you use the beam as part of you wiring system by definition it becomes exposed conductive part (by strict definition use common sense)
supplementry bonding is in addition to main bonding
