Howard, They do want a circuit breaker, and its not hardwired but plugging into an existing connector and the target equipment plugs into this. Why they wont just change out the circuit breaker is beyond me, but I think it comes down to...the end user wants my ex to provide something as part of the delivery so they don't have to mess with electricians and such...just plug it in and let it go. Lets just say....the end user is a very large worldwide corp, and to get them to just run into someplace and do it simple.....is never simple. Ive done a couple of these where its been bid out as thousands to just wired in a connector and junction box. Amazing what the gov't will spend.... I'm still waiting to hear back if the end user will demand it certified or let it be 'part of the overall system'....

So pretty simple....box with a breaker, and two connectors. So the customer is in England, and they want to try and avoid the certification process by saying...all the components are certified, so we don't need to do this assembly. At least thats they way they will propose it to them. In case they don't buy off on it....anyone know what kind of certification (is there a reference number) would be required for a "breaker/disconnect" box? Oh....they want to have a breaker on L1, L2,L3 AND neutral. Told em...no reason to have it on neutral....Oh we want to have it just so they wont whine about it....hmmmmm, but I guess if its acting as a disconnect, thats OK. It's not that complicated - it has to be CE marked, that's it! It's impossible to buy anything here that isn't. I take it the thing will be hard-wired, not plugged in? Do they need an actual circuit breaker (that trips on overcurrent conditions) or just an isolating switch? If the latter, they're easy to find - See: http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=150196958170 If it needs to be an overcurrent breaker, Farnell have these: http://uk.farnell.com/jsp/Electrical/Thermal+Types/MERLIN+GERIN/C60HB420/displayProduct.jsp?sku=1421093 I take it your ex-employer isn't in the UK? Otherwise they could just nip into the nearest electrical supplier and buy the switch or breaker and a box to house it in.
