Tricky tight rope - Negative opinions ..

You get what you pay for, (and some local wholesalers risk a big hit , when they have to honour their returns policy)

710? I had 41.1 in mind. I'm curious how those voltage cutoff values were derived.
Yes I missed table 41.1 maximum disconnection times on page 55 as far as how are the voltages are derived starts with AC and DC theory

I’m trying to learn the UK ways of doing electrical work
 
UK wiring requires that general socket and lighting circuits trip a breaker in a required amount of time based on the line to earth voltage.

We can test breakers or RCDs but we can’t fix them if there are 1/10th of a second to slow, as far as I go if they trip I’m happy. I read your profile and I applaud you for wanting to learn but don’t just post things you are reading and asking why. I’m here to help anyone that needs it if I can. I’m going to ask you a question are you from the UK or US

If you are looking for reasons why the code wants this or that is something every body wants. You have hundreds of people who make up rules and regulations in the BIS 7671 and they all have different opinions
