Is the length the 53' tub to disconnect plus the 55' disconnect to panel for 108' ? The 53' is the 6/3 and the 55' is the 8/3. Canada. | |

| Sep 10 at 12:40 | comment | added | Retired Master Electrician | @FreshCodemonger - Your length is going to get you about a 3% voltage drop from the panel to the tub which is right on the edge of acceptable for motors. Also if you are using the entire 43 Amps as a start up adding 25% will get you to 53.75 Amps. That means you are stressing your 50 Amp breaker at startup. Are you running this in Canada or the US? Is there a maximum circuit breaker size on the name plate? I still recommend you check with your AHJ. | |

| Sep 9 at 22:23 | comment | added | Fresh Codemonger | Name plate rating for the hot tub says 43 amps / 230 volts / 60 hz. Hot tub is 53` of teck cable from hot tub to disconnect. Disconnect to panel is probably about the same maybe 55`. | |
| Sep 9 at 22:20 | comment | added | Fresh Codemonger | In Canada, teck cable is defined by CSA standard C22.2 No. 131[2] and carries the type designation of TECK90, the 90 referring to the maximum conductor temperature in degrees Celsius that the cable may be used at in a maximum 30 C ambient environment without de-rating its ampacity. en.wikipedia.org/wiki/Teck_cable | |
