![]() 212 forum posts 16 photos | I'm looking to site my Transwave rotary converter out of my workshop. Firstly I don't have a suitable floor space for it and secondly, if I put it anywhere else, the vibration is too much - ie on top of a cabinet or on a shelf. So the thought was to site it outside in a waterproof box or cabinet. Anyone got any thoughts on this? and, of course, where I may get one! Matt |

Don't they have louvred sides presumably for cooling which won't work well in a box. They do - but was anticipating either a larger cabinet or some form of ventilation. General limiting factor is that the depth (internally) need to be 450mm and then I'm going to have to use a rightangle 3 phase plug. I had thought of a garden box but I think I may end up making something - just need to try and make it resilient to the elements. Maybe a mini garden shed or lean to with lining....

![]() 2110 forum posts 565 photos | If you put it outside you may have to put in a small tubular heater and thermostat in the enclosure to keep condensation at bay, have done similar for compressors etc in the past. You can wire a cooling fan if necessary to cool down equipment as well. We just knocked up a wooden and board structure with plenty of room and loovered door David |

Keeping the rain off and stopping fog and temperature changes making the guts damp are different things. Electrics don't like damp, especially 400v electrics. Given the cost of replacing a rotary converter and the dangers of wet electrics, that worries me a bit too. Certainly not an insoluble problem but I think there are a number of questions worth asking before deciding on a solution:
Matt's options are much wider if he lives on a farm and can put the box in a sheltered private spot. A different arrangement would be needed if the converter and wiring was to be located next to a public pavement in the window box on the weather side of a London flat. Dave |

2536 forum posts 24 photos | It has to be said that every cable company, no matter who built the network does exactly what is being discussed in their streetside equipment cabinets. They all have mains in them and they can all be touched by the public. Some get slugs crawling over the cct boards Nothing dies except the slugs and I don't believe any cabinets catch fire. The worst thing that happens is single skin ones bake in the summer sun, which kills the batteries. |

![]() 6956 forum posts 229 photos | Cable cabs don't have mains or even the ELV, it's normally 48v, and all the electronics are in sealed boxes. The telephone wire terminations are the only exposed elements which is why they can suffer from noise on the line. |

1346 forum posts 15 photos | I have a 10hp R/c to power my workshop. I mounted it on an angle iron frame,screwed to the wall,one to cut down on the noise by being mounted on a shelf [this was a no-go,too noisy ] The second reason was to save floor space.. There was still some noise from it,not a lot,but this was solved by fitting a plywood cover,open at the bottom. To date this has worked well,noise is very little,damp is not a problem. I would say,keep it inside,too easy to have it knocked off,and they dont come cheap. |

I have some high density foam and was thinking about mounting it on that which in turn is on a board which is then screwed to a frame. I am thinking about boarding the loft space in the garage and so if I mount the frame above that I maybe able to save on the noise as well. Remote switching of the RC will be OK (have checked!) By the weekend I should have formed a plan!! Thanks for all the input - I have decided against an outside box ......
