Looking for some advise.

A commercial,kitchen getting some new appliances all single phase and ss benches.

Existing power not in the correct positions,flush boxes.
Walls are clad with pvc sheet, stuch to reinforced concrete wall
3 options

Plastic conduit drops to surface boxes, do you get plastic hospital saddles?

White trunking to surface boxes

Or dado trunking

I like the dado option from a cleaning point of view,but havent seen it in a commercial kitchen before?
Anyone

I think I'd prefer conduit drops, myself. However, I've never seen plastic hospital saddles before, come to think of it, neither distance saddles.

Dado trunking might not offer the amount of IP protection required in a commercial kitchen possibly due to warping. if run above places where excessive heat is produced..

Plastic is not suitable for the environment of a commercial kitchen. It will be very hot at times, particularly up near the ceiling.
Also, if the walls are clad with PVC or stainless steel panels this is usuallly for cleaning.
I have designed commercial kitchens with these and no surface wiring was permitted. Any conduit or trunking will gather dust and dirt allowing germs to breed.
It was a requirement of the local licencing authority, so I would check with them or the client if there are any such requirements here before you install anything.

I would expect either galv conduit or SS conduit depending upon the environmental conditions.

In one of the recent commercial kitchens I worked on it was designed so they had allowed for periodic cleaning and washing down - all walls were plastic or stainless steel faced. All sockets were MK master seal with RCDs, machine isolators were minnimum IP55 either with PVC conduit or surface wiring SWA was used with waterproof glands.

The distribution boards were all located in stores area or non food areas.

Hope this helps

I would agree with the statements made by other respondents but then, how many pub/hotel kitchens have I seen where plastic conduit has been used.?...,

The last one I quoted for ended up being rewired in plastic conduit by he brewery electricians !

If it's too hot for PVC conduit, aren't the PVC singles in steel conduit equally dubious? (or doesn't it get that hot?)

Sorry, its not near any heat from cookers, its where, microwave, soup urn and coffee machine is and a low level hot cupboard.
No issues near sinks etc
Current install is a mix of everything apart from dado

Not hot enough to melt plastic conduit I would think! (nor plasic trunking or cable insulation for that matter)

if there's plastic sheet on the wall i would think plastic conduit would be fine if not too close to direct heat sources.
