Quick update, I was on a job today doing work for a company that specialises in HV and LV electrical and switchgear etc.
As I pulled up outside I seen they had a sign with HV Transformers on it and immediately I thought, welder! So I asked the question about my issue and he asked what type of MCB it was I was using and he immediately recommended changing out my Type B MCB for a Type C or even D as they are more lenient on the inrush. I haven't bought one yet, because daddy duties, hopefully Ill get one tomorrow and replace the Type B and see what happens.
Seen that the other day, didn't make much sense but I was reading it in the wee small hours after reading the replies on here. I was indecisive between C and D. Still am to be honest so I'll go with a C over the D for now and see how that works out.
pity u haven't a clamp on ammeter or cant borrow one to see what the inrush current is on start up I just had to use mine on a 10 hp powerwasher motor that was tripping on start up and had to alter the breaker to suit
Treat me stupid but would most/all MIGs that can produce up to e.g. 165a not have the same inrush current when set at their highest setting or does it differ depending on their internals?
I could buy one but I dont see the point on it to use it once, but then again I could use it for car audio.... but that's for a another day
What are the implications/limitations of using a D over a C type MCB in a residential setup?
