Think mine was 3 days but that was 25 years ago.
You really need to be doing the course IMO. It’s not really needed if you are already a competent spark and can read a book, but it will be helpful for the detail.
A qualification helps to prove competence if ever needed.
Very little does have complete shielding, most SY CY is worse than SWA. If the OP is unnecessarily paranoid about that, use a foil wrapped cat 6 but the uplift in cost of that and the equipment would be a waste in this instance IMO.
I’ve posted up Mitsubushi already, also another brand I’ve used a long time ago below.

I’ve fitted the 2nd link into a board as they were the exact same frame/mould as the obsolete board. (The name escapes me)
Have you done basic motor testing? IR? Are the windings balanced?
Are the terminations secure in the plug and socket?
You won’t see a current spike on a clamp on, the sampling time will be too large at a guess.
‘very’ inductive items may need type D. Obviously you need low enough impedance to achieve disconnections times when choosing the type.
Calculate it before installing or wing it and test which I’m sure it will be the latter.
Getting 2 4mm SWAs into the back of a metal clad sounds like fun but...
What country are you in? This sound odd.
Edit - I not familiar with your code and I did not fully digest the wiring at 0400 but that would not be allowed here.
W - is this N or your ‘ground’. If the latter it’s switched. If it’s N you should not be connecting that to the chassis.
Looks ok to me, reactors up front (line)
are used if you are very close to the supply transformer, not because you have 2 in parallel so that will not solve your issue. Basically adding impedance. Only used them once where the panel was sited 50m away from the HV/LV supply.
What size and...
Perfect, it has to be quiet as it in the loft above the bedroom.
The Mitsubishi was on a long lead time so they recommended this.

Crap, totally forgot about the condensate but I can get a little diaphragm pump from work. It cannot go on the outside unfortunately.
I intend to install the pipework through some soil pipe to match the downpipes/vent pipe so can run a flexi down that.
Warranty requires fgas cert, this will...
Anybody have AC?
I’m looking to fit one in the bedroom as working 12h days/shifts is not pleasant on 2 hours sleep.
I will install myself and pull in a favour from the fridge boys/contractor at work to commission as they are F gas registered.
1st choice was a cheaply generic unit for 500, but...
