fuse mod which disconnects neutral

spidersparks · Jan 13, 2014

Evening guys, I got a job at the moment that requires a bit of scheming, I have some gas fired fan heaters that need to have a permanent supply for the fan inside them so they don't over heat etc, they then switch on from a control wire simple stuff, what I need to do is have a local isolator for each one but the the permanent live can not be turned off unless it's being serviced and this is in a public place where people fiddle with things! What I'm after doing is to put in a single mod plate in with a double poled isolator for switching just the control wire only and I'm sure I've seen these and this is what I need help with locating, a fuse carrier which when the carrier is removed it disconnects the neural as well as removing the fuse, now I'm hoping I haven't dreamed these up and making a plonker of my self but if someone has seen one and can point me in the right direction appreciation and plaudits shall be received
Many thanks in advance
David

Can't you just install an isolator that can be locked in the 'on' position as well as off?

Rotary isolator for instance Marvo.
One with sufficient number of poles to kill the supply and control circuit?

If you are trying to fit a mechanism in a single gang plate then you could fit a double pole key switch for maintenance (though they are not isolators afaik) and a single pole switch for the control wire. If you need something fused then use a triple gang single plate and add a fuse carrier.
