Hi ,
Had he anorak on the other night and posted this .
Section 608.
Protection against direct contact cannot be by placing out of reach, or by obstacles.
Protection against indirect contact cannot be by seperation, earth free equipotential bonding, or non conducting location.
Pitches preferably connected by underground cable (swa), away from the pitch itself unless it has extra mechanical protection. Overhead conductors must be completely covered with insulation ? , 2m outside the vertical surface extending from the horizontal boundary of any caraven pitch , and 3.5m up in the air, except where there is vehicle movement, then it must be 6m. ( best bury it ).
The pitch supply equipment should be placed adjacent to the pitch, and not more than 20m from any part on the pitch it is intended to serve.
Socket outlets must be IPX4 and to BS60309 ( dimentional interchangeability requirements for pin and contact-tube accessories of harmonized configurations , commando skts and plugs). They must be put between .8m and 1.5m from the floor to the bottom of box. Current rated at 16A and there must be at least one socket outlet per pitch. Each socket must be individually protected by an overcurrent device, also, RCD protected individually, or in groups of no more than three. They must not be connected to the PME terminal.Depending on the nature of the supply there are different earthing requirements, and to finish, grouped sockets should be on the same phase.
I suppose that 13A load per single outlet should be allowed for really, and that would be @299A !!! . Diversity would be a factor I suppose but knowing our summers there could be heaters in use !
Sorry this post is a bit 'heavy going' for my first, but there may be something here you may have overseen. Sounds like an interesting good job.
3yr advised test rate too.
N-joy.
Ed.
