Changes that need to be made for the next 2011 NEC

Hopefully, someone or I will get these in by November of 2008 for the 2011 NEC.

1. Motors for R/V's need to have overload protection and disconnects regardless of voltage. Presently these RV electrical systems' low voltage circuits escape the NEC by being part of the automobile electrical system. Motors used for tip outs are now burning up at a rapid rate and sometimes they take the wiring harness with them. Something needs to be done.

2. R/V manufacturers should be required to provide an electrical diagram with the R/V's. Presently they are not all doing this and it is a nightmare to try to work on these electrical systems.

3. Greenhouses. Where receptacles are used in green houses to provide power for auxiliary equipment they should be protected by a Class a GFCI. I have watched at least one worker working on a wet floor with a frayed extension cord dragging in water as they run a vacuum cleaner in a greenhouse. This needs to be addressed.

4. Cathodic Protection. Impressed current cathodic protection systems are not included in the NEC. The Canadian Electrical Code does include them. These systems are used extensively to protect oil industry tanks and pipelines. The conductors are often mistaken as grounding conductors and vice versa. Something needs to be done.

5. Natural Hot Springs. What are they and what do they become when modified with liners, pumps, and electrical lights. I know of at least one such spring that is an accident waiting to happen. We have all heard of swimming pools in Mexico and Puerto Rico electrocuting several swimmers at once. Let us hope this doesn't happen in Alaska at Chena Hot Springs.
