So Hard wiring is the only way to accomodate an RCCB Rated higher than 30mA

Apparently the NIC said as long as the commando skt is clearly labelled as for Specific use ONLY then its fine????

Even when fixed in a secure concrete pillbox on the jetty? (I know this might be a stupid question and I apologies, but I'm not qualified and I'm going in tomorrow to tell guys that are what I found out so I need to be 100% to tell an engineer he doesn't know what hes on about :| )

Each Inverter has its own 415v socket and 100Ma RCCB

The sockets are individually protected. The RCCBs have only tripped few times in 4 months. Could this not be nuisance tripping? Also I'm sure 100ma RCCBs were recommended by the equipment Installers. I wasn't on the job so I'm just going on what I've been told. So this was wrong already?

A company I work for have Installed a 3ph supply to a Distribution board on a Jetty. The Board feeds 2 415 Commando Sockets through C20 MCBs protected by a 4 Pole 100ma FP RCCBs The Sockets feed Inverters for some kind of Zip wire water activity. Anyhow, there seems to be some nuicence...

My garage is fed from the non-rcd side of my CU. The 3 way board in the garage has a 2 pole rcd main switch. does the swa, running under my concrete path need Rcd protection itself? or is it ok as it is?

Does that apply to the 10mm earth bonding the gas and water?

Thankyou.

What would you suggest? The wall may even be tiled yet.

Is there a problem with running (chased,capped and plastered) cables down a upstairs bathroom wall to feed outlets in the room below?
