Hi, I recently purchased a car lift to put in my garage and what I found is that if I plug it into a socket indoors (via. an extension lead) everything is fine, but as soon as I plug it into my garage plugs it trips the garage electrics, so all the plugs and lights go off. The installer who put the car ramp in said that this was often the case (he said it even before he started installing) and that I needed to change the Eaton 16A Type B to a 20A Type C mcb. I have four flick mcb switches - two of which are marked ‘lights’ and the other ‘sockets’. I changed the socket one to the one the installer said to use and it still doesn’t work - so I wanted to check... 1) is the change I’ve done already a usual thing (16A type b to 20A type c) - don’t just want to take the installers word for it? 2) Would I also have to change the light mcb to 20A Type C - I didn’t do it as assumed they were on different circuits. 3) if the answer to 1 is fine to change and 2 is no the light mcb doesn’t need changing, then do I need to increase the socket mcb from 20A or something? PS Rang the car ramp place and they said try a 32A C breaker - I’m worried that they are just blindly telling me to increase it, what about the impact on my electrics overall, I don’t want to compromise safety!!! Thank you.
