Is the hotel electrician easy to do? Who did this?

If you have comprehensive skills, you can do well. If the store is large, the work to be done is as follows: the power distribution room, distribution transformer, all power supply and distribution lines, generators, water supply equipment, all electrical appliances in rooms and restaurants, including TV, electric heating, air conditioning, refrigeration and lighting, all equipment in kitchen and cold storage, and elevators-must be well maintained and done. It may be difficult to do without comprehensive technology, and a small shop may do better without too much work. For reference only.
