Upgrade 2.0

Hi!
This is my CURRENT SETUP:



Eventually, my 120W LED will go out and I will have/want to replace it for something stronger.
This setup hasn't caused me any trouble so far...been 2 years.
Voltage of my electricity is 220.

These are the setup's I have in mind:

1- Replaced 120W LED for 250W HPS




2 - Replaced all for 3 x 400W HPS





So, the 2 questions are:

A - Is it safe to mount 1,510 Watts / 7 A on a single 25 A Circuit Breaker?


B - Is it safe to mount 1,210 Watts / 5.5 A on a single 25 A Circuit Breaker?





Thank you for any ideias and suggestions.

No one can tell me if it's doable or not? I'm nowhere near an electrician....
