I've just bought some 2.5mm H07 cable so I can install an extra 240v socket on my boat. It is really nice to handle compared to the blue artic cable used for my current shore lead. It's floppy so easy to coil, especially in this cooler weather.

Any downside to replace my current blue shoreline with h07 rubber instead?

Probably not, it's what the entertainments industry uses for lighting cables.

BS7909 2011 Code of Practice for Temporary Electrical Systems for Entertainment and related Purposes, recommends the use of HO7 RN-F cables for outside use
 
Technically H07 is what you should use for shore power cables, arctic is the grade most used but it is not rated at 250v for outdoor use.

If the spec for Arctic cable reads:

Applications:
For use outdoors and where flexibility is required at sub-zero temperatures. The cable remains flexible down to -30°C. Low voltage household appliances under medium mechanical stress.

Conductors:
Plain annealed flexible copper

Insulation:
Arctic grade PVC (Polyvinyl chloride)

Core Identification:
2 Core: Blue, Brown
3 Core: Brown, Blue, Green/Yellow
4 Core: Brown, Grey, Black, Green/Yellow
5 Core: Brown, Blue, Black, Grey, Green/Yellow
7 Core: Black Numbered + 1 Green/Yellow

Sheath/ Jacket:
Arctic grade PVC (Polyvinyl chloride)

Colour:
Blue, yellow or orange (other colours available on request)

Voltage:
300/500V

Operating temperature:
Maximum 70°C
Minimum -30°C

Minimum bending radius:
3 x diameter

Short circuit temperature:
160°C

Standards:
BS6004

Can you please explain why it is not rated for 230volts for outdoor use . :confused: :confused:
 
I changed to H07 RN-F when my bollard changed to 32amp and I was changing to thicker cable. Had thinner arctic prior.

Had it over a year now, no complaints and nice to handle.

Rolec use it for all the under pontoon cabling too.

It's meant to be tougher, flame retardant, higher max temp of 85 and more oil resistant than arctic.

Abrasion resistance is lower than H07

"USE OF ARCTIC CABLE - Ref BS7909 2011 Code of Practice for Temporary Electrical Systems for Entertainment and related Purposes
Arctic Blue able can often be seen outdoors at events. This is not recommended in BS7909 2011, despite its widespread use.

So it is adequately rated from an electrical point of view and would be satisfactory where it is not subjected high levels of abrasion, such as between a boat and a nearby pontoon shorepower outlet.

I can see why something with better abrasion resistance would be the better choice for use at "outdoor events" where it may be trampled on, possibly even driven over!

Thanks.

I know from countless live events that ho7 will last for a long time despite being driven over by forklifts, cherry pickers and trucks though eventually it will go bang and let the smoke out. :)
It's also used extensively for powering 3 phase chain hoists.

I couldn't help but agree if it weren't for the fact that I see so many leads trailed from a post the other side of a pontoon with feet and trolleys trundling over them and the leads chaffing on the boat as it moves about or chafing between fingers.
 
or me the primary benefit is it HN07 is soo nice to handle/coil compared to the artic flex. As it's so floppy it also less likely to form a trip hazard. Can it come in different colours?

It is so much nicer isn't it, but as Henry Ford said (or at least was reported to have said) you can have it in any colour you like, just so long as it's black.

The polychloroprene used for the sheath is degraded by a number of common substances ...... including urine ... so don't pee on your shorepower lead or you might get an interesting surprise :eek:

That has been dis-proven by extensive "behind the generator" latrine studies at countless fairgrounds,:D
