Discussion Overview

The discussion revolves around the components of an electric control panel for a pump, with participants sharing their knowledge and concerns regarding safety and qualifications in handling such equipment. The scope includes technical explanations of components and safety warnings related to electrical work.

Discussion Character

  • Technical explanation
  • Debate/contested
  • Homework-related

Main Points Raised

  • One participant expresses a need for basic information about the components of an electric control panel, specifically asking for names to further their understanding.
  • Another participant warns about the dangers of working with electrical panels without proper qualifications and supervision, emphasizing safety concerns.
  • Several components are identified by participants, including contactors, circuit breakers, auxiliary contacts, current transformers, relays, motor rated overload trips, miniature circuit breakers, cartridge fuse holders, and plug-in relays.
  • Concerns are raised about the quality of workmanship in the panel, highlighting issues such as incorrect wiring and potential safety hazards.
  • A participant mentions being forced to work on the panel as part of their university program, despite having no prior experience in electrical work.

Areas of Agreement / Disagreement

Participants generally agree on the identification of components but disagree on the appropriateness of the original poster's engagement with the panel given their lack of experience. There is no consensus on the safety of the current setup, with some expressing serious concerns.

Contextual Notes

Participants note various safety issues related to the wiring and assembly of the control panel, indicating a lack of adherence to proper electrical standards and practices. The discussion reflects a mix of technical identification and serious safety warnings.

Who May Find This Useful

This discussion may be useful for students or individuals interested in electrical engineering, particularly those learning about control panels and safety practices in electrical work.

hey ... i am working on Electric control panel for pump

but the Problem i am new on this Field

all i know in this Electric control panel is conductor

please can you help me to find References explain Components of Electric control panel

or just anyone tell me the names of Components

hi there
happy new year :)

considering that you have confessed to not knowing anything about this panel, you shouldn't even be playing with it without qualified supervision !

If you haven't already started an electrical trade, then you should be.
Working with mains voltages and a panel this complex requires that you have suitable qualifications, not only for your safety but the safety of those making use of its functions

As a result it would be unwise for anyone here to give you just enough info to risk personal injury or property damage

hey davenn

all i need is know the name of Components to learn more about them

that's it>>>>
 
Google circuit breaker, contactors + auxiliary contacts, relay, main circuit breaker, current transformer.
thats all I recognizes form your pic.
 
do you mean :

1- contactors

2- circuit breaker

3- auxiliary contacts

4- current transformer

5- relay

am i right ?

thanks dude ... you are the best
 
1 - Motor rated Overload trips
2 - Miniture circuit breakers (mcb's)
3 - Cartridge fuse holders
4 - Contactors
5 - Auxillary timer unit (Clipped onto a contactor)
6 - Current transformers
7 - Plug in relays and bases
8 - Dinrail mount terminals

Ps who ever connected this up is a bit of a bodgit IMHO as they used an Earth coded cable as a phase wire and 2 generations of colour coding is present within the same unit (incoming blue is on a new colour code cable and represents neutral where-as the panel is wired old colour code hence blue is phase colour), really poor workmanship, as well as derated cable size tapped onto incoming live terminals without fusing down, another worry is where its incoming earthing although may be connected outside of visual field seems to be missing?

Is this part of a "hands-on" school course?

If his answer to the above is in the affirmative, that would explain a lot. :smile:

dlgoff . the thing is i am Student of food process engineering

but my University force me to work on that Electronic Control Panel

i told them i have nothing to do with it .. they told me you are not Graduate until done this work

anyway thanks you all for help me

I said it at the start
and I will say it again

This is a great way for some untrained person to get electrocuted and may also others using equip powered by this panel
because some one who doesn't know what they are doing has played with the panell!
