    Hw many computers for no RCD

    Multi skilled maintenance engineer. Started as mechanical engineer but mainly repairing electric motors for D&M. Added electrical work later. Where I am now I mainly do electrical work. My thoughts exactly on the risk assessment which is why I don't think I will see one.

    Hw many computers for no RCD

    The designer isn't doing the installation. If there is a risk assessment I won't get to see it unless I demand it. I will most likely be the installer as I work permanent nights so can be done when no one in the office. I want RCBO as at the moment there are other things like Xmas trees...

    Hw many computers for no RCD

    We have to put two new tower sockets in to a office at work. At the moment we have two towers but four sets of four desks. The two sets of four without towers are fed via extension leads hence the need for two new towers. I have been told by our tech guy we aren't fitting RCBO on the two new...

    Rewiring maintained emergency lights be non emergency!

    I miss read that. What you can do is take the wires going from the pcb to the battery and put a switch on the live. Just done something similar with a scrap twin spot that mate wants to use in his garage. He can charge it up at home then when he needs it switch on and with no supply it will...

    Powering electrical components with static charged electricity

    Short answer no. Static has been know of for many years. The only use is for a vandergraf generators in school. Standing on a plastic box and make long hair sticks out. Or all standing holding hands and zap the last person Lots of fun but not very practical

    Electric ac induction motor 50hz to 60hz?

    No don't think so as the unit will see an imbalance and shut down

    Electric ac induction motor 50hz to 60hz?

    That would be the way I would do it. Three phase pumps are better quality and more efficient. But you have to factor in the cost of new pump if you allredy have a good one. Proper single phase to single phase are good enough to run a pump. I understand not using cheap speed control they very...

    Electric ac induction motor 50hz to 60hz?

    Yes look for single to single. Either that or look for three phase pump. Which would be more efficient.

    Electric ac induction motor 50hz to 60hz?

    Something like this. Ebay UK number 265213284360 Slightly more than £50 but best going slightly more on the kw rating

    Electric ac induction motor 50hz to 60hz?

    Google the kw volts and vfd/vsd. When you get it set the parameters to match the pump you have and the drive will do the rest.
