Mike, et al, Thanx for mentioning my name; by now you should be able to
tell the stories as we’ve talked thru these things before.
From my experience, protection is primarily needed fo

Yes, I've seen these 30 mA RCDs or RCCBs before, but not an RCBO

Google can explain these acronyms).
I've even recommended these for large machinery. The ones we used had
adjustable trip points up to 30 mA. Note that I recommended these for
Hi Mark,
I’ve seen mains filters used for 400 V 3 ph. 200A services with leakage
currents close to 30 mA. Consider that RCBOs commonly used outside North
America have a design trip current of 30 mA, so leakage currents above 30 mA
will cause the RCBO to trip. None the less, these large leakage

Interesting question!
I would agree with 3.5 mA for cord and plug connected stationary equipment up
to several HP. However, note that 8.2.6e) of 60204-1 describes cord and plug
connected equipment with leakage above 10 mA.
However, I think that a quite large piece of machinery that
Hello,
Is there a hard limit for leakage current for machinery in the EU? IEC 60204-1
provides instructions in clause 8.2.8 for "equipment having earth leakage
currents higher than 10 mA". This seems quite high so we have applied the 3.5
mA limits for class 1 stationary equipment in IEC
7 matches
