Hot Tub wiring
I am installing an outdoor hot tub and considering the wiring that is needed. The GFCI panel as an 30 and 20 AMP breaker and the instrictions state that a 50amp breaker is needed on the main panel of the house.
When I look up 50 amp services it always suggests that I need #6 guage for the live and neutal and #8 for the earth, however the wiring instructions from the manufacturer show #8 for the live and neutrals and #10 for the ground. The diagrams also show "WIRING ILLUSTRATION 203VAC, 40A, 60Hz" but a 50 amp breaker is shown.
Can anyone help me understand why these would be different?
Is it anything to do with solid or stranded wire?
