This might be a really dumb question, but I know very little about electricity so please forgive me. I have a 3-phase 208V outlet the requires a C14 to C13 power cord. I have C14 to C13 power cord but the power cord says 10A/120V~ on it. The equipment I have only draws 6 amps on this outlet, but I'm wondering if it's safe to use this power cord since it says only 120V on it? Does this mean 120V for each phase so it's okay to use it, or can I only use a 208V power cord for this?
