Hello , I just recently bought a hot tub, It called for a 50 amp 6-3 wire with 50 ampl gfi sub panel. I ran the 6-3 wire sealed into the Electrical conduit , brought the wire into the house, wired everything up , and when I turn the breaker on ( in the House) then turn the breker on ( on the subpanel, the subpanel trips. I've wired the 50 amp breaker in the house as follows.

Red on top of double breaker
Black on bottom of double breaker
White , on White Buss Panel
Ground , On Ground Buss Panel

On the GFI sub Panel, It is wired as follows

Black ( from house ) into top screw of GFI Breaker
Red ( from House ) on Red Buss in sub Panel
White ( from House ) to White Buss in Sub panel
Ground (from house ) to ground Buss in Subpanel

Black ( from Spa) to Bottom Screw ( black) on GFI Breaker
White ( from Spa) to White on GFI under white pigtail on GFI breaker
Red ( from Spa ) to Red Buss In sub Panel
Ground ( from Spa ) to ground Buss in Subpanel.

The White pigtail that is attached to the Breaker is attached to the White Buss

Everything looks fine, But When I juice it up the breaker trips, I've tried Taking the " load " off the breaker by disconnecting the Spa and it still trips I have 10o Amp service in my house , and the 6-3 total run from house to sub panel to spa is about 48 feet any sugestions? Dave

White ( from House ) to White Buss in Sub panel

White from house needs to go to the pigtail on the GFCI breaker.

Load neutral (screw on GFCI breaker) should drive white isolated bus in sub-panel.

You CANNOT run cable for the outside portion of this circuit. You MUST run individual conductors with an insulated green ground wire.
