20 Amp mains supply
For the instalation of air condition in my home, Global Cooling requires a mains supply of 1 x 20 ampere to the external condensing unit
What does this 20amp supply consist of and how is it installed? Where is it attached to the mains of the rest of the house? Is there not a 13amp limit in most ring circuits? Thanks, Antonio |

Thanks, Antonio We had the same installed here some 10 years ago and all we did then was to run a lump of 2.5 T&E from the mains board consumer unit via a fuse to a surface wall outlet and the Aircon company took it all from there. FWIW that was to the inside near the indoor unit the outdoor unit what does all the work was just the other side of the wall and they took whatever cables they wanted outside via a rotary isolator switch. -- Tony Sayer |

It'll just be a 1.5 or 4mm^2 cable from the consumer unit or fusebox. NT |

Thanks, Antonio They want to install, or you to install, a 20A MCB in your consumer unit, and run a cable from there to the external unit. The part of the run that is outside should be done in exterior rated cable like hi-tuff http://www.tlc-direct.co.uk/Products/HT2dot5slash3.html as this is suitable for outdoor use. You will need a double pole isolator switch outside (Here is an example of a triple pole one - this would be fine to use)http://www.tlc-direct.co.uk/Products/CMDX020.html), near this unit, so you can probably install this isolator on the wall and run the exterior grade cable from this to the condenser, then you can use the cheaper twin and earth "indoor" cable through the house back to your consumer unit.

That was a most helpful reply. The problem that I have is that the consumer unit in my house is in the garage quite far from the intended location of the condenser, three stories higher and on the other side of the property. Is new cabling strictly required or can I use the 2.5mm twin and earth already in place that feeds the power circuit in that floor nearby? I wonder about the potential overload. Thanks, Antonio |
