I have the older model mobile connector, MC240, which is limited to 30A. I know that the newer version, the UMC, supports 40A with the NEMA 14-50 plug. I've been reading through the forums and see reference to modifying the MC240, often with mention of the Roadster Foundry Mobile Charger, which seems to be the basis for Tesla's updated UMC. I've seen a post or two mention that the MC240 can be modified; that the only reason it was limited to 30A was because that's the largest GFI available at the time it was made. There was reference to simply removing the GFI to enable full 40A charging. Event through I'm neither an electrician nor an engineer, that just doesn't seem right. Are there any instructions available to enable more amps out of the MC240?
