Recs for Extension lead please
To safe my marriage, I need to move my new beer brewing machine from kitchen
to bathroom - that's a mere 10 metres for an extn lead. The maximum heating element drain on the brewer (if that's the right word) is 2200 watts. The following Youtube guy, has been banished to the garden (in February !!), he's using an extension but hasn't mentioned the extensions' rating. See Brewday # 1, fast-forward to about 18 minutes :- https://www.youtube.com/results?sear...ndering+brewer So what's the minimum rating for a suitable 10 metre lead - 10, 15 or 20 amp please. TIA. |

It happens that Harry Bloomfield formulated :
10amp should cope with that. But usually it will be a 13amp rated extension. Make it is supplied via an RCD and the lead is fully uncoiled too. |

Thanks all, it looks like the bathroom is not a good idea, although the bath itself is fibreglass and some distance from the shower unit. There's a small covered area (porch), reachable from the kitchen with a 10 m extn lead. Probably the best bet. Thanks John, the Jojo 10 m extn 13amp looks a good price for about £15, which includes vat and a £3.50p handling fee. |

I wouldnt do it that way myself, too little control over the temperature and so makes the brewing too badly controlled.

The issue of unwound extension cables overheating has nothing whatsoever to do with *inductive* effects.

The reduced dissipation rate results in a much higher temperature equilibrium being established in order to dissipate this waste energy into the environment. Furthermore, copper having a significantly positive temperature coefficient of resistance which can create a runaway effect, will aggravate this temperature rise in an unwound cable to a surprising degree. So much so that anecdotes about such wound up cables being turned into a welded mass of PVC and copper are quite common. -- Johnny B Good |

I start rewinding by tucking the double socket into the centre, so it has to be fully unwound to use it. The highest load so far is under 1kW, so not much on 1.5 mil. -- Peter.

Malcolm Race has brought this to us :
A cassette lead isnot a good idea as the lead needs to be fully unwound for this rating, to avoid inductive heating. With acassette lead there will always be the temptation to wind in any spare. Many do think the problem is inductive, but there is not induction because the flow in the live, is cancelled by that in the neutral. The problem is the resistive heating. The cable warms up because of resistance, the close coiling limits the ability to dissipate the heat and the cable melts. |

Use of the shower is not a problem as showering's take place pre 9am and post 9pm. My last kitchen brew had spillage issues and the tops of the walls were soaking. Inadequate extractor fan and a small window is the main culprit. The bathroom has a ceiling mounted Velux window and a powerful extractor. |

With Winter approaching, brewing in the bathroom is becoming more attractive. Yep. I personally do mine in the spring and autumn so I dont have to heat or cool the brews. But I normally do about 10-15 brews at once so I get it all done in a couple of weeks in the brewing run so it isnt very desirable to heat or cool the brews while they are brewing. I attempt to do a full year's brewing run at a time, so it normally works fine even if one spring or autumn turns out to be not suitable for brewing because it changes from too cold to too hot too quickly. Clean-ups will be easier from within the bath. I dont have a bath, only have a shower. If I remove the shower rose, connect a 6' extension, I can then use 60C water from the GCH system. This saves a lot of time, as the Brewer only has to raise the temps to 67C (mash) 80C (sparge) and then the final 90 minute boil stage. I use the canned brewing concentrate myself.

The latter puts much less thermal stress on the installation. I'd recomend that the OP gets a 13 A rated 10 m extension and ensures it is fully unreeled. There might be ones with a resetable thermal cutout, lest he forget... It is an important point if you are going to run close to the rated current through a conductor that it must not be still be rolled up. We have had problems before with the church tea ladies using an extension reel to boil 2x 3kW kettles with only about half the cable out. It melted the insulation and internals of the reel before any fuses blew. All the village hall extension cables now have thermal cutouts on them. -- Regards, Martin Brown |

Speed blabbered, again: Yes it is. I fill the other room intended to be the second bathroom with the bottles in milk crates. I have 75 of them now, and 20 soft drink crates http://www.precimaxplastics.com.au/gallery/ https://www.dropbox.com/s/jx60jsq9a9...24_75.jpg?dl=0 Those are for the 750ml full sized beer bottles, what we call long necks. I still have the 375ml beer bottles we call stubbies and the 32 Kitab crates I keep those in but don¢t use those much anymore.

I still have the 375ml beer bottles we call stubbies and the 32 Kitab crates I keep those in but dont use those much anymore. I've got about 200 x 500ml dark swing-cage bottles. About 5% are clear, just to keep an eye on things. I've only got 10 stackable crates, so most bottles are kept on shelves, with some strips of black plastic to keep the light out. Consumption is only 2 bottles a day, so two 40 bottle brew-days per month, keeps me ahead of the game. |

I use longnecks because this area has a very high percentage of Italian immigrants who are into doing tomato paste every year, so quite a few show up at garage sales as some old italian falls off the perch and their kids get rid of the bottles. Just missed out on a full pallet of 200 last week. About 5% are clear, just to keep an eye on things. I've only got 10 stackable crates, so most bottles are kept on shelves, with some strips of black plastic to keep the light out. Consumption is only 2 bottles a day, Yeah, I normally drink a 750ml long neck a day. Half before dinner and the other half with dinner. so two 40 bottle brew-days per month, keeps me ahead of the game. I prefer to do one mega brewing run every year or so so I get it all done in 2 weeks or so. |

Close enough that the DNO was quite interested in daily plots of voltage whilst the primary was on the back up feed. This was after an engineer had called, seen the plots and measured the voltage which agreed with my reading at the time. There happened to be other engineers at the 11 kV backup feed orginating primary substation, they gave 'em a call and got that knocked down a notch. That did bring our voltage down to 253 ish but only for about 24 hours. Not overly surprising as the distribution system is a balancing act of transformer tappings, line loss and regulators. Drop the line voltage and everyones voltage drops. There is a regulator in the back up feed and that ought to keep the 11 kV it feeds on to the primary at the correct level. Looking at the date (2014) on this plot: https://www.flickr.com/photos/allsorts-60/44881990212 I suspect they gave the regulator a hefty kick shortly after the 33 kV was back in use as I've not spotted any serious voltage fluctuations since. We sit at 240 +/- 5 V pretty much 24/7. -- Cheers Dave. |
