Thus you need to be well planned because you have less than one month in your hands and you want to see one of the best electrical devices being installed in your home.
So to avoid any mishap which may cause unaffordable delay, you must make a trip to the electrical fitting components store nearby and come back with a bagful of following stuffs :
Bolts : While fitting some electrical devices, you need these look-like-rod-in-shape components. They come with external threads which help other components with internal threads to make a support.
Buy a set of bolts consulting the electrician. The set must include bolts of all types such as fully or partially threaded, long and short ones. Also buy a variety of bolts on the basis of their varying thickness.
Clips : When fitting certain things like cables and wires, lead-acid batteries, fuses etc, you need them to give them a sufficient support system which can hold them tightly. Thus don't forget to buy clips, These are available in a wide range as per their usage.
Conduit Fittings : Your electrical wiring needs electrical pipes for a sustainable protection. And in the same way these pipes are needed to be given a support base to avoid any breakage in future.
Also these pipes need extra care so they don't fall down. Thus not buying conduit fittings seems impossible. Buy a set of all the types of conduit fittings such as; electrical boxes, expansion fittings, sealing fittings etc.
Electrical Fasteners : While your wiring goes on, you need to join a number of electrical circuits and and connect various electrical objects together. For this purpose, the electrical fasteners are used.
Moreover, they help you to give proper alignment to the objects. Have a detailed look on your needs and buy electrical fasteners as per need. A lot of varieties as per their usage, design, shape and size and the metals used are available.
Electrical holders : To fix certain things like light bulbs, batteries, lamps etc and to provide them power supply, the electrical holder is an urgent thing. These are available in various shapes and designs which may make the wiring process much exciting.
However, I must say that this list doesn't include all the electrical fitting components you may require during the wiring. But the list include all major and important ones. Some other stuffs you may need are; electrical terminals, electrical mounts and rails, wire nuts etc.
