Son Agro 430 watt ballast Question

[Andy]

Just wondering whether 3 Son Agro 430 watt ballasts will fire up simultaneously on a single 15 amp circuit. I see that each ballast runs at 4.55 amps. That's 13.65 amps for the three. Will I require extra amperage at start-up or is the quoted amp draw for start-up.

Thanks,

Andy
