I have also noted that the Earth Leakage current can vary significantly. My worst experience was connecting a LAN between two systems (with individual ELC<<3.5 mA) and watching the ELC rise to more than 8 mA.
Even powering them both from the same isolating transformer made little difference - Some you loose: some you loose badly.
