Actually…jeff he did not state anything about the main panel being within sight or near the tub. The general question was if a disconnect is required and the answer is yet. It was made more clear in 2002 NEC to remove the issues of the lighting receptacles and so on to narrow it down to service issues and safety.
Hey brother…we all can be wrong once…You more than make up for it in your ZINCO lessons…
Ahh…I got ya…on your question…well the code specifically says : Each means shall be accessible and within sight from it’s equipment.
The intent of the disconnection means to be installed within sight of the spa and hot tub ( pool for that matter ) to allow service personnel to disconnect the power while servicing these units. This requirement ensures that a disconnect is available at all times to workers servicing and equipment such as motors, heaters and control panels. This was revised from previous NEC sections in the 2002 NEC.
The idea is…is your panel TRULY in sight and if so…is it ALWAYS accessible in all cases…what if the door is locked, you can’t be their when it is being serviced and well the list can go on. The concept of putting the disconnect within sight of the unit means it is always accessible…without the chance of it not being accessible…Hope that explains it better.
