Safety Issue

[jsolano]

I work in a Containers Handling Port. Recently a Corrosion Protection System was installed by a contractor.
During the inspection I could see that 480 V lines runs under the quay.
For maintenance purposes the electrician will be in contact with water (during high tides). Beside this there are control panels installed under the quay with transformers, controllers, etc. but each of this panel has not a main breaker even a fuse that disconnect the entire box. My concern is that if an accidental contact ocurs when an electrician is working there, they do not have the oportunity to disconnect it...since the nearest breaker is in the substation over the quay.
Which article can I use from NEC to re-design this system.

Thank you for the support !

Re: Safety Issue

The NEC does require a means of disconnect for most equipment. This means of disconnect is generally required to be readily accesible and with in sight of the utilization equipment it disconnects. A main disconnect that de-energizes an entire panelboard may not be required. For example, if a feeder serving a panelboard is protected at its supply by an overcurrent device not exceeding the rating of the feeder conductors or the panelboard, a breaker or fuse is not required at that panelboard.

In any case, an electrician should not be working on the equipment energized, so he shouldn't even be near or at the equipment while it is energized.

Re: Safety Issue

Are you saying that an electrician could be working on De-energized equipment while there is a 480v. Energized line running neaqr the workspace?
Why not use line hose or blankets on the 480 line?
