Hi all,
Little about me. new to the forum and new to the industry. I have been a data engineer for 2 years specialising in fibre but I always wanted to go into power so I committed to it and paid for the course. I have completed my level 2 and unfortunately my level 3 has been delayed due to the virus.
A friend of mine got a job installing power for an additional 4 aircon units (we have already installed one for the client). According to the aircon installers, they want 3 on a 16a breaker, 1 on a 20a breaker and the one already installed is on a 20a breaker. Before knowing the sizes I suggested fitting a 63a breaker and have that feeding a sub board next to it with all the air con breakers in (There isn’t enough space In the existing board). After knowing the sizes I am now unsure if this will work, and most importantly, be safe. I then spoke to some friends who are electricians and one suggested fitting a Henley block to split the feed into 2 have have both boards on a 100A main switch. This seemed to make sense and looked like a way we could do it.
I am now wondering if I can fit the 100A main switch in the existing board and have it feed the sub board with just the aircon RCBOs inside?
I hope this makes sense? If not then please ask. Or if you know of a better way it could be done then please let me know. I am still very much learning and am open to any advice.
thank you,
matt

Also, the property is a domestic house, 3 phase supplying the house which feeds a board in the garage (the one I’m working with) and multiple boards inside. I am still yet to find the wattage of the units to find the design current (the aircon installers said they usually run at around 6 Amps which I’m struggling to believe as all the ones I could find online were over 2.5kw which is just over 10A.
I have also looked at diversity but there is nothing specific to aircon. There is power & heating or space heaters and they’re the closest options.
