Changing domestic rcd from a 16amp to a 32amp

[stinka]

My stick welder blows fuses over 100 amps

No, it's got a standard 13 amp fuse domestic plug into standard socket in garage. The garage has its own board with a 100amp mcb and the sockets have a b16 16amp rcd.

So I'm thinking of swapping the socket on the wall for a blue 16 amp socket with same 16 amp plug on welder.

Can I swap the rcd easily enough for a larger 32 amp one So I can crank those Amps well past my current 100 amp limit ??

That last but should say 13amp limit, not 100amp

The RCD you're replacing is there to protect the existing cable size. Is it on a ring ? You can see by opening the consumer unit and see if there's a pair of wires on that fuse. While you're there see what size cable it is.

Cable comes in one wire from consumer to double socket on wa, it's in truncking and it's 10mm so 53amp

No probs then change the RCD

MCB's are available in a number of surge ratings, generally type B C and D.
The vast majority of domestic installations use Type B.

The .2 second ratings are:
Type B: 3 to 5 x Rated Current
Type C: 5 to 10 x Reated Current
Type D: 10 to 14 x Rated Current

Type D breakers are commonly used on large motor and welders.

So ideally you need to change the MCB for a C or D type of the SAME current rating, as the MCB is sized to protect the wiring.

Had garage built 2 years ago and had 16 amp plugs put in for my welder.Was on 13 amp with old style breakers.The new 16 amp plugs turned out to be worse and have now gone back to 13 amp.Best thing to do is hard wire it to 30amp supply.

isn't the problem with welders that they are an inductive load an create a sudden surge when you first switch them on? not sure how to solve it, but I will watch with interest
