“4-square-air-conditioning line, change it all!” the worker, in one sentence, left the owner of the house with the shell on the spot — change it, the wallet hurts; instead, it's always smoked at night. To look at this mess, there are two questions: 1. Is it really necessary? 2. To what extent is it not to lose
First of all, the conclusion is that most people, the 4 squares, are enough, but the “sufficient” has borders. If the house is equipped with 1. 5 hangers and the line is short, the four squares are the perfect luxurious version; once it is replaced by three cabinets or one towed multi-central air conditioner, four squares can be replaced by “tight belts” and alerts are buzzed as soon as the engine opens in the summer, and the liner temperature can roast the eggs. The workers moved, mostly to put the worst in front of the table — he was afraid to turn back and take the fall himself。
In other words, three hard indicators must be clearly identified: number, distance, number of years. Large, far away, old houses, one in three, is worth a step up to six squares; two in two, starting directly at six squares; and full, don't worry about the money, six squares plus one step on the independent road. Don't use "possibly air-conditioning" as an extra space on a home-type map, and the circuits are insured, and when it comes to adding, it's more expensive than buying copper。
Breakers have to follow the line, like couples. Line 4 squared with an open range of more than 32a, 6 squared within 40a, with a possible “naked run” of a single level. Too many strange combinations of 63as, 2. 5 squares of power lines have been seen, the wires have burned the switch and the fire alarms are too late。
It's not too much for the scene: kitchen plugs to save the dozens of metres of squares, microwaves, dishwashers, steambox wheels, 2. 5 squares, which are like putting cement on a primary school student; a four-square circuit behind the living room television wall, with projectors, ps5, and air fryers; lighting with 1. 5 squares, but remember that the lights are not tied to the plugs, and the black screens are off at night。
Powerful and weak sub-trucks, vertical vertically, tube-protected, sound like a site slogan. Don't turn the pipe too fast, leave a little radians, and then try to switch the wires so that they don't cry for their mothers; leave an extra 15 centimetre in the box and change the smart switch in 10 years without breaking the wall。
Finally, to those who hesitate: the wire is a one-off investment, buried in a wall for 20 years, and the expensive hundreds are distributed every day, without even a cup of milk and tea, and you can blow air-conditioning and brush your phone in the hottest night. It's not worth it. There's an answer。
