I think the concern expressed is that 20a (16a in your case) is significantly more amps that 8a. My point is that as long as the wire is OK then it's OK. If you were to do 3p and have 24a or 4p and 30a then you get to a level that might melt the wire. But 16a won't hurt 10awg wire.
The other concern expressed is just that any electrical current >40v or so carries the risk of shock that can harm you - so the same respect you would use for 120v or 240v home wiring should be employed / respected. DC can be just as deadly as AC in shock terms.
