--- Quote --- You should have a seperate Fuse rated @ 7 x the normal operating current --- End quote --- which would also require the cable to be uprated,under the uk regs that would require a motor circuit pulling 5A needing to be protected at 35A,and instead of 1mm cable more like 4 or 6mm,a substantial increase in material costs.much simpler to use a slower fuse type designed for motor circuits. |

I also checked The Mitsubishi service manual on this Model Number its a Rotary Vein as I said . Look at the Plate .below of Dave's Unit . He has the top Number which is non inverter . The VHI is the inverter Model . Dave plate shows this SRK35ZSA-W . 51 years in Service building & HVAC I think I know how to read an AC serial Plate . Thank you. |

So on a UK Ring mains which is 2.5mm in a loop will be equal to 4mm assuming middle of loop (ring) Small AC could be plugged direct to socket as UK plugs have internal fuse .13A . |
