fixing to install a 122 and livescope on the front and 2 102's at the console, later I will add another 102 to the front possibly. i had all my Lowrance units 2 gen 3 12's, a gen 3 9 and 3d ran through a factory rotary swith that is a 20 amp on the console. im running 8 gauge from the battery up to the console to a 6 fuse bus panel and going 10 gauge to the units and livescope box. will that 20 amp switch be enough to carry the load of all that? its a convenient spot to cut power to all the units. anyone see a problem with this setup or something I need to do different? also on the livescope garmin said it doesn't need to be out of water no more than 10 minutes or it starts to heat up, can you put the unit in standby or sleep mode and it turn the livescope off running to different spots?
