cable width for wiring thermostat
My Dad is installing a Danfoss RMT 240 volt room thermostat to control
a Danfoss HS3-3 point mid-position motorized valve. Would 3 core and earth 1mm cable have sufficient current carrying capacity for this application? Thank you for your help. |

Would 3 core and earth 1mm cable have sufficient current carrying capacity for this application? Yup. The motor in the valve only takes a fraction of an amp, and 1mm is rated at 12 amps. -- *Out of my mind. Back in five minutes. Dave Plowman London SW To e-mail, change noise into sound. |

It's physical robustness is more significant than its current-carrying capacity in this context. Rick |

Yes, but don't lose sight of the fact that - in a Y-plan system - the 3-port valve switches the boiler and pump on in some modes, and the current for that *also* goes through the room stat - so it's not *just* switching the valve. Even so, 1mm cable should be ok. -- Cheers, Set Square ______ Please reply to newsgroup. Reply address is invalid. |

We're still talking small currents. A 5 amp fuse is fine for most systems. -- *The man who fell into an upholstery machine is fully recovered.* Dave Plowman London SW To e-mail, change noise into sound. |
