Hotend fuse max rating

Hi,

I can't seem to find what is the maximum current rating for hotend heater driver?
Can I replace 5A fuse for hotend with slightly higher rating (up to 7A)?

Thank you in advance

24v x 5a = 120w ... why do you need more power than that?

ps: Q1, the hot end driver FET is rated 100 amps ... lol.

Schematics here: you should be able to find part numbers of things like connectors by searching.
