Hi boys,
Having sorted a few issues out around the new hoome, and ripped all of the very dodgy electrics out of the garage to start a fresh, I come here in peace to ask for a little advice.
The garage in question is 10mtrs long by 8.5mtrs wide, with a gable roof. Unfortunately in some respects it is located some 70mtrs away from the CCU at the front of the house, but this also means its located quite some distance from other properties, so noise won't be too much of an issue. Originally, the garage was fitted out in T+E simply clipped to the walls, no CPC was used on any of the earth bonds, and MC fittings were used throughout.
As mentioned above, I have ripped all of this out, as personally, I believed it was unsafe, and the views of the Electricians who apparently re-wired the house thought it was unsafe also as it was not connected to the CCU.
The feed to the garage also looks to have seen better days, and disappears into a Metal connection unit to the rear of the property, so I am also in the process of pulling this out to upgrade it at the same time. I will be using 10mm 3 Core SWA for the entire run from the house CU to garage CU, will this need to be protected by RCD at the house end, or am I safe to only protect the garage by RCD at the garage end?
I am now looking at using PVC Conduit throughout with correct fittings installed where required, which leads me to my first question. I will be using 20mm Rigid PVC Conduit and 2.5mm Stranded Singles for the install, what is the total capacity of the 20mm conduit?
Second question, if labelled at the CU and outlets, what would be the maximum number of Ring Final Circuits I can install in the garage space? I am currently looking at 2 due to the distances between the work bench locations, and possible loadings.
I have started to compile a list of the circuits I will be installing into the garage, of which I have listed below, any advice on them would be greatly received:
1x 6a Lighting Circuit for Main Garage - 8x 1500mm 85w Fluorescent Tubes
1x 6a Lighting Circuit for Internal Store Room - 1x 1500mm 85w Fluorescent Tube
1x 10a Lighting Circuit for Outside Lights - 1x 150w Security Light, 1x 300w Security Light, 1x 75w Metal Halide
1x 16a Radial Circuit for Battery Chargers - 3x Double 13a Metal Clad Sockets
1x 16a Radial Circuit for Internal Store Room - 2x Double 13a Metal Clad Sockets
1x 16a Radial Circuit for Compressor - 1x 16a Socket, although I would like to leave this available for upgrade as I will soon be getting a new motor for the compressor as 3hp is a little on the light side.
1x 32a Ring Final Circuit for Workbench 1, located on the west face of the building - 6x Double 13a Metal Clad Sockets, 2x Metal Clad FCU's for Parts Washer and Shot Blasting Cabinet
1x 32a Ring Final Circuit for Workbench 2, located on the east face of the building - 6x Souble 13a Metal Clad Sockets
1x 16a Radial Circuit for Electric Hoist - Located in the centre of the roof line
I would also like to install some 16a Sockets around the various benches too, along with 1 between the garage doors, so that I am able to use welding equipment at various locations. Would these also have to be protected by 16a MCB's, even if 2 were connected together at different points of the garage?
Final question, before I get the credit and debit cards out to pay for everything, I am looking for pipe clips to suit the 20mm conduit, I have had a look around all of the local DIY stores to see what they have on offer, unfortunately only 15mm & 22mm, and I have also spoken to the local CEF, who have informed me that they are available, but they would like to charge me £28+vat for a box of 100. Can anyone recommend a supplier for these?
Apologies for the long post, I'm sure there will be something I have missed along the lines somewhere.
Many thanks,
Steve
