[QUOTE="boltonsparky, post: 506013, member: 4678"] Don't do many consumer units and since amendment 3 the ones I have done I've done top entry with trunking and the fireproof stuffing glands so the consumer unit would contain the fire. Curious to know what others do on rear entry CUs. Seems pointless to fit a metal clad if it's got holes in the back that are open into a wall or a floor above because that's where the fire is going to go. I know of one manufacturer who makes bespoke CUs that offers a rear entry panel with intumescent sheet that seals the cables as they enter the rear of the CU. I've also found a manufacturer that makes decent sized intumescent strip that may work for reasonable money but when they charge £16+vat to deliver a £5 item it's a bit pricey to buy just to have a look at. I've seen people using fire mastic and although in theory this works it just looks cowboy even though it's hidden inside the CU. No point asking the wholesalers round here, most of them look at you blankly when you mention a type A RCD. Interested to know what, if anything, you use. [/QUOTE]
