power outlets in a shed

[car10002]

hi

have a shed and just wondeing out of the cms plug in electrical that jayco use for their vans or just using a couple powerboards what would be better.

if using powerboards would have a double pole power point with overload protection and have a powerboard each end of the shed with ext cord plugged into each side of the double pole double power point. also would plug the lights into them too.

if using the cms electrical system then would have following

single power point by middle door for a plug in light

double power point by lift up door (one side for plug in out security light, one side for a plug in light)

either a single power point by back door for plug in light and a single power point inside back end for plug in security light or a double by back door (one side for security light and one side for plug in light)

2 double power points at front (one each side)

1 or 2 double power points at back

so all up 6-8 outlets for appliances and 5 outlets just for lights

how exactly does the cms system work and whats better out of the cms system and spreading powerboards using 1.5mm2 extension cord.

whats quality of the cms system and how easy is replacement components to get.

thanks
