Anyone know of a good blueprint desiging software that I can also form layouts of wiring, such as wiring coaxial electrical and other things.
Needs to be free, and be downloadable and usable without internet connection.
I'm redesigning the wiring of an existing house that is 40-50 years of age.
Would need to be easy to use.
I've found a few things but I want to know of a well known software that's safe and works best and is trusted. dang i didn't know you could do that with auto cad
I dunno how i have it but somehow i have the full version haha, never used it but once though.
it's so expensive so i still dunno how i came by it Dang can't find the hard drive i have it on, any other ways??

Good electrical design is more than delivering a system that works and much more than switching components on and off especially when controlled by PAC or PLC controllers. The designer needs to consider the following availability, efficiency and installation costs as a minimum in conjunction with functionality. Often circuits can be replicated on the principle of 'it isn't broke it don't fix it' however it may not be broke but could it be improved? Is always the attitude that should be taken when creating electrical designs? One important point to always consider is that the manufacturer's data sheet this will be key, and consulting component manufacturer is often essential, to ensure that electrical designs can meet the grade for CE marking.
When designing any system it is important to consider the system lifecycle of all components and the maximum availability without detriment to the equipment. Often there is more than one way to wire a component and in many cases this will not affect the overall performance, however this does not mean components should be thrown together, when considering a standard motor circuit containing a drive, contractor and circuit breaker. It would be possible to wire the system with the contractor before or after the drive, and both cases would work however the lifecycle of the drive will be significantly increased, by fitting the contractor prior to drive and if failure of a contractor was present could even cause damage the drive. The above is only one example of component general layout and manufactures best practice should always be considered right down to the recommended fixing torque. There are many other ways which will also increase availability; one such design would be thought the reduction of relays and replacement with solid state devices, as mechanical devices only withstand a maximum number of operations. There are many components on the market that will allow for more reliable switching.
Power quality is also an important consideration and the machine directive on EMC is a good starting point as odd harmonics, not only decrease component lifecycle but cause in efficiencies and in sever cases can result in hot neutral's where usefully power is feed directly to ground.
System inefficiencies can also be eliminated at the design stage, it is estimated that a poorly designed system can waste up to about 10% of the power consumed. Looking at the switching frequencies will determine the best switching method, often this is only a guide at design stage and it is important to evaluate all systems for energy consumption on a regular basis. Inefficiencies can also be minimised by switching of components when required, a control relay and PIR (Person in Room) may be seen as unessential component but could save thousand over the product lifecycle.
Using the same designer, panel builder and Installation Company is always a way of ensuring that the most efficient design is achieved, traditional methods have resulted in design and panel build by one contractor, PLC software development by another contractor and installation by another contractor. All of these different sources can be an excellent way of achieving the best rates on labour but often the design will not be the most efficient. If a system designer was in tight competition for a job he would often target the system hardware at a lower cost to get the job knowing full well that the cost of installation would be much higher. Selecting a principle contractor and allowing for them to subcontract will always result in an overall more efficient design which will best utilise all modern technologies in the full system. As the cost of copper increases and the cost of distributed control systems with remote I/O modules increase the full project should always be a major consideration.

If you want to be a building designer there is a three day electrical course in the UK that will teach you how. The course runs from 9am until 5pm each day, with thirty minutes for lunch. Its a great start to your design career.
The electrical course is created for those involved in the specification and design of low voltage installations of electrical products. The topics included are the principles and practices of over current protection, and the principles and practice of shock protection. The electrical design course also includes the studies of switching and isolation, the selection and installation of electrical design equipment and a look at some special installation and location. At the end of the classroom training students will participate in a design exercise in which they work on a real installation, applying all that they have learned in the three days.
The primary objectives of this electrical course are to introduce its participants to the legislated and regulated requirements of IEE wiring, according to the governments BS 7671 statute. Instructors will explain how this regulation is applied in electrical practice, with emphasis on electrical design and specification.
The course starts out with some background on the regulation, including its impetus and a look at the particulars of its precepts and its terms. Defining them for the students is part of this chapter. The next part of the electrical course, Chapter two, looks at the general characteristics and importance of electrical assessment as it pertains to regulation BS 7671, and why it is important to determine all the installation parameters that apply.
Chapter three looks at the way to protection yourself and your client against overload or fault current. Chapter four then discusses the factors you must consider in selecting wiring systems, the details of the requirements for live electrical conductors and cables, and the actual application of the principles of over current as learned in chapter three of the electrical course. Various constraints in the process, such as determining the size of live conductors and the drop of voltage, are learned as well. Students are also trained on the techniques they must use to economically size live conductors as a group circuit, fulfilling specific conditions.
In chapter five electrical course participants learn the switching and isolation requirements of the federal electrical mandate, and the ways they can meet those requirements. Next they learn about the legislated process for protection against fire and thermal effects, as well as how to protect themselves and their clients from under voltage or over voltage. Safety products and services are covered in this part of the electrical course too.
Once the students have learned all they need to look at and put into play in order to satisfy the governments BS 7671 electrical requirements, they are then introduced to the ways in which they would inspect compliance with the legislation. They learn how to verify compliance initially, how to gather the necessary test data and other information, and how to prepare and deliver the design certification once compliance has been adequately proven.
