if the neutral and earth of the flex are touching together they will trip the rcd out even with the fuse removed from the plug . But what you are doing does not sound safe.
Edit
Westward beat me to it :)
Clamping a peace of wood inside. Before drilling may help prevent dislodging the knockout . I have not use fuse box so dont know how secure the knockouts are.
If you have spare normal open contact you can send a 24v contactor coil supply through the normally open contact Then you will need to fit a push to break switch on the same circuit to reset the contactor
We do industrial and commercial sites we get charge about £450 for a visit to remove the flash pads . It the same if there are 5 DBs or just 1 . We use a company called oakmere group.
if the scenario is that you have a long lead with a 16 amp plug on it supplying say a porta cabin and just by unplugging it you have provide safe isolation so you can work on the other end, 50 meters away I would say this is not safe isolation as any tom dick or harry could plug it back in, if...
Agree with westwood That SWA need terminating correctly. I would give a code 2 for that. I would also code 2 those exposed single insulated cores of the SWA . To fix the HI zs though you would have to down rate the main fuses, fit a main upfront 300ma RCD at the DNOs supply box Or run in a new...
I would say the one in the ops photo is Chinese.,going by the Chinese writing on the rcd unit. I would also be concern that the metal din rail is not connected to the earth bar . Agree with others,there is s log of doggy stuff for sale on Amazon, so would be very wary of this product
I used to have a transit connect. It has a hatch that goes under the passenger seat to get 3 meter conduit in etc. Only room for tools and basic van stock though . I put a false floor in one I had to store my steps under We used to get all materials delivered to sites though so did not need big...
The NIC dont write the rules
Different assessor have different options
And the QS,s pass on there guidance. I would say Ring testing is required. I am always seeing broken ring circuits on EICR test results
I see 3 options.
4 way to mccb panel
Ryfield unit
or bus bar chambers with 2x 100 amp switch fuses or with some DBs you can fit a mccb to use as the main switch. Schieder is one example I know of.
I have not come across many scenarios when i can omit surge protection . If Anything is going to be more expensive to repaire that the cost of the surge unit. Then I fit one. For example high level light would expensive to repaire if scissor lift was required.
Agree with Dave disconnect unused
Phases on the outgoing side of the isolator. No reason to replace mcbs with single pole, unless you need room in the DB to add other circuits and it also sounds like the loads of been spread out over the 3 phases so all good there.
