Scrap cable stripper......
I do seem to acquire a lot of cable, usually because it is overordered, (not buy me) Or strip out quite a bit, got a load of 120mm armoured to strip ATM, an this only cost me about £20 for the motor off eBay. I had everything else or made it, I've got an inverter on it to control the speed. Had...- Rocboni

Scrap cable stripper......
Heres my homemade one, can do upto 120mm singles or armour cores (not tried anything bigger) Also does T&E on the other side but never really use it as it's hardly worth it.- Rocboni

Load regulated feeder control
Heres one for you automation gurus. I'm looking to control the speed of a rotary feeder or conveyor that feeds a hammer mill on a farm. In order to achieve maximum efficiency the feeder needs to be regulated via the load of the hammer mill. The 55Kw motor on the hammer will be started using a...- Rocboni

Contactor issues on ceiling heater circuits
Is the stat mechanical? Has the stat got a neutral wired to it, the neutral is used for the return for the anticipator. This is a small thermistor type device that kind of pre-heats the bi-metal strip, reducing 'hunting' and making the stat more efficient. I may not have explained it completely...- Rocboni

New supply to factory
The new switchboard would require a 1000Amp feed although it would only be around 4-8M in length from the incoming position, although it would not be easy to connect into the 1970's dorman smith 1000A MCCB busbars. Anyway not going to happen i dont think- Rocboni

New supply to factory
Hi Marconi, I am leaving it to the contractors, I know the tri rated tails will just be thrown in to the busbar chamber and onto the main switch already knowing that that capacity of the main oil pot breaker will be exceeded one day, however I have informed my superiors and they are not...- Rocboni

New supply to factory
I'm not proposing removing the old gear, just installing new to supply new extension as well as future issues. Possibly take off some of the lager switch fuses and supply via new switch board thus minimising impact if there is an issue, eventually the old questionable oil breaker could be...- Rocboni

New supply to factory
Money is not really an issue to be honest, shut down would be carried out a night. The new extension is not populated with machinery and wont be for another year or so. The worry for me is when the extension is fully kitted out with milling equipment they start getting random tripping, who...- Rocboni

New supply to factory
It is only for the supply of the new extension however i am questioning the way in which it is getting done as i don't think the 1940 switchgear is capable of supplying reliably 600+amps, it is already drawing 170A and the main dash pot breaker is rated at 600A this could be turned down inside...- Rocboni

New supply to factory
Hi, sorry it is quite hard to describe, but ill try my best. No, they are leaving the exiting set up alone with the old PILC singles feeding the oil filled breaker (this is fed from busbars protected by the 1000A dorman smith MCCB) Paper wrapped Cables then come out of the oil breaker to...- Rocboni

New supply to factory
Just wondering what people thoughts are on obtaining a supply to a part of a local mill where I am now a maintenance engineer. The existing installation is terrible with many switch fuses that have been added over the years, the oldest part is from 1946. The total supply capacity in question is... -
