Connect PIV to lighting electrical circuit?
Looking to install a PIV (positive input ventilation) unit in the loft.
Spec says max draw of the unit is 16w. Technically/legally can I connect this into the lighting circuits accessible in the loft space? If so would a switched fused spur be in order? Or something more? (Or less :-) ) TIA -- Jimk ----Android NewsGroup Reader---- http://usenet.sinaapp.com/ |

(Or less :-) ) If the makers instructions say it needs to be fused below 6A (or whatever the rating of your lighting circuit MCB), then you would need to connect via a FCU with appropriate fuse... (in reality a switched FCU would be a better option anyway since it gives a nice place to break into the circuit and terminate the connections without needing to do it at a ceiling rose, which probably has enough wires already). -- Cheers, John. /================================================== ===============\ | Internode Ltd - http://www.internode.co.uk | |-----------------------------------------------------------------| | John Rumm - john(at)internode(dot)co(dot)uk | \================================================= ================/ |
