It's a Wylex, as is the sub-board I'm fitting, so a reputable make. But amusingly, when you fit an RCD as opposed to just an isolator in the Wylex NH series 3 phase boxes, you have to buy a little 'kit' with extra links and DIN rail to mount it. Included is a clear plastic cover for these links with a label pre-attached saying something like 'disconnect supply before removing' BUT THEY STICK THE LABEL ON UPSIDE DOWN :clap: I've fitted several of these boards with the kits - the screws holding the insulation clear cover are asymmetrical so it can only go one way, but the first time I found it, it had me puzzled for quite a time trying to fit it. Now I just peel the label and stick it back the right way up :ddb: |

Firstly this morning I replaced the risers of the flow and return pipes that got kinked yesterday, and removed the faulty RCD for when the replacement arrives. On the bench, pressing the RCD 'Test' button introduced no leakage current - it's supposed to put a resistor from the lives to neutral to introduce and imbalance and trip. To prove my theory I did the same test with (admittedly a single phase) spare RCD and could measure the resistance when the button was pressed. OK it's definitely faulty ! Then I drew up panels to mount the flow and return water pipe terminations on the verticals that I've welded to the building structure and cut them on the CNC plasma table and trial assembled the plumbing that turns them through 180 degrees and gives a barb fitting for more flexible hose leading to the chiller itself. The hex nipple in between the two elbows doesn't give enough separation, but the running nipples that I have on order haven't yet arrived. . . . now off to paint the panels ! |

OK panels painted, now twiddling thumbs waiting for deliveries ! . . . and while typing, the coupler for the chiller pump feed pipe, and the full length 1" BSP socket to fix the bore hole pump have been delivered :clap: So I set about cutting the leaking Grundfos feed pipe and solvent welding an extension on to allow me to install the universal coupling - but the solvent weld will have to dry first. |
