It might be, but current draw isn't the only concern - a given voltage spec typically means insulation is designed around that voltage, and arcing and shorts can happen even with zero current being drawn (even if it is more likely as things heat up). It depends entirely on how overbuilt the insulation is. I don't like to take any chances whatsoever with AC power (12VDC on the other hand, that I trust enough to mess with), so I wouldn't use anything with uninsulated terminals as close together as the ones seen on the photos for those connectors. At the very least I would pot the terminals in nonconductive epoxy or similar after soldering - there's barely room for heatshrink on those by the look of them.
