Hi All,
Still planning the power feed from house to workshop.
Yesterday I took the new (but old, GE metal 5 way) RCD CU that I got off eBay out to try to find some MCB's for it. MK and Wylex ones were 'close' but I think I would prefer the right ones (anyone got a 32, 16 and 6A one in their van to sell?). I was then just going to get a Clipsal garage RCD CU (like the Screwfix one) but they said they were out of stock, weren't getting any more and suggested Clipsal were in the mids of a change of ownership or summat?
That took me to a DP switch (CU to workshop feed isolator) and found a white plastic (7 quid) 45A cooker switch (with neon) but was considering what I was going to mount it in. I say this because I'm not sure why I wouldn't want to run the SWA the extra 3m under the house floor and up near the CU and into some sort of metal box (better for the gland etc, rather than buying a junction box and doing the extra 3m in T&E?). I do have a smallish DP switch and fuse in a metal box with gland holes (ex Dads garage) that would take the SWA nicely, but I wouldn't need the fuse if I'm taking the feed from a 32A MCB in the CU. Could I re-wire the fuse carrier with some heavier (than 32A) wire or possibly bypass it alltogether?
Lastly, and assuming I want to do some Stick / MIG welding (13A worst case) at the end of say the 15m length of SWA, what would the 'ideal' size for the SWA to minimise too much voltage drop (without going mad ) please (6mm?)?
All the best and thanks for your time ..
