[PSES] Suggestions for SOHO Frequency inverters?

2022-02-03 Thread Oliver Betz
Hi all, can anyone suggest inverters in the 300..500W range suitable for "non-industrial" environments, i.e. with low emissions and low leakage currents (mains plug, RCD compatible)? Most suppliers seem to only target industrial applications and don't bother with bench top devices. TIA Oliver

GFCI = Ground Fault Circuit Interrupter RCD = Residual Current Device In North America, GFCI’s typically are included in an outlet that is part of a branch circuit. The GFCI may have a number of outlets downstream. Under normal conditions, the residual leakage current in the downstream

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 for cord and plug connected equipment where the earthing/grounding is not considered

Doug -- Thanks for mentioning this! Yes, I've seen these 30 mA RCDs or RCCBs before, but not an RCBO (confused? 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 MACHIN

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
