Air compressor - hobby mechanic and painting

[MetalMonkey]

I wasn’t ever planning to but just wondered why? Are they just pushing the boat too much?

3-5
5-10
10-20 times and all that sparkery stuff

It takes a lot to trip a Type D, all MCBs can handle a surprising amount of continued overcurrent, so it is not a good idea to put in a D unless it is necessary.
I've had a nuisance trip on a C but that is very rare. Often a manufacturer will state if a Type C or D breaker is required.

One thing you can do which is sometimes handy - put in a 32A feed to a commando socket from a standard 32A type B breaker and then make up a breakout box (like the caravan hookup things) that plugs in with a couple of 16A type C breakers in and a couple of 16A sockets.
The advantage of this is it gives you two protected outlets and finding Type B breakers for an existing consumer unit is usually a lot easier. If you are not hammering both outlets at once the Type B should handle it.

Cheers chaps. I hadn't considered the electrics and am still yet to put them into my new garage so I'll spec in some 16A sockets if I can. I'm planning on running the supply from a fuse boxed brick outhouse to the garage. Might even house the compressor in the outhouse (used for boiler and storage).

I'm defo going to be looking for a belt driven one now I see the advantages. 50l might be enough for my needs - I'm unlikely to spray a whole car - just the panels I repair.

With db normally 6db is doubling, but if you are working with a power then 3db is doubling. 3db is doubling of sound power, but our hearing response is not linear so it will not appear to be twice as loud to an individual.

Thank you for that reply I stand corrected and have learnt something as well.
