When a fire occurs, the heat causes the intumescent material which lines the hood to expand and fill the void between the lamp and the hood. This seals any gap in the ceiling and therefore maintains the fire rating of the ceiling. text/html 2009-10-17T00:11:40+00:00 http://www.diynot.com/wiki/electrics:installation_techniques:micc?rev=1255734700&do=diff RF Lighting's guide to terminating MICC cable. You will need: From left to right: Pot (this one has an earth tail), pot seal, gland, potting compound, joistripper, pot crimper, stub sleeving, pliers. Step 1: Cut the cable off square. This can be done with a junior hacksaw, a ringing tool or sharp cable shears. If the MICC is old, cut 100mm - 200mm off the end. The magnesium oxide is hygroscopic, and will have absorbed moisture. You will not be able to get a joistripper started … text/html 2009-10-05T22:23:15+00:00 http://www.diynot.com/wiki/plumbing:faq:faq36?rev=1254777795&do=diff IN the news - again. If the thermostat in a hot water cylinder fails, the cistern (tank) in the loft can soften and dump 250kg of near boiling water through the ceiling.

Balancing procedure: You will need either two clip on pipe thermometers (£12 each) or an infrared thermometer (about £30 from Maplin). I have used both and prefer the infrared as it has a faster response, is more accurate and can be used for other things, e.g checking the temperature distribution over the surface of a rad. text/html 2009-07-14T20:02:21+00:00 http://www.diynot.com/wiki/electrics:hs:pic2?rev=1247598141&do=diff Thanks to sar2012 for this one.
