These days, every house or apartment is going to have an electrical system of one sort or another. Understanding the basics of these systems will help you evaluate homes and knowledgeably answer questions from prospective buyers.
Electricity typically is generated at a power plant and travels to transformers, which lower the voltage to a level that local distribution systems can handle. From there, electricity travels over local distribution systems to individual homes.
One problem in this method of delivery is that quite a bit of electricity is lost in the process of traveling from the plant to its final destination. An alternative is generating electricity on site by solar electrical systems, wind turbines, or generators.
So what else do you need to know about electric systems? While it’s best to leave the big questions to electricians, these are some basics that you should know.
- Does the home have 220 volt service?
On the off chance that the house was as of late constructed, the answer is quite often yes. Most houses today have two 110 volt wires and one nonpartisan wire running into the house from the neighborhood dispersion framework. These wires can run underground or over the ground. On the off chance that there are two 110 volt wires racing to the house, then the house has 220 volt administration and machines, for example, dryers and aeration and cooling systems.
More seasoned houses were typically worked with 110 volt administration; if the electrical framework hasn’t been redesigned, it won’t be conceivable to utilize some displays of apparatuses (however options can be found).
It’s conceivable to update a house from 110-to 220-volt administration. The amount it expenses to overhaul will rely on upon the specific house and the area. In the event that a purchaser is occupied with updating, a circuit tester can give an assessment for what the work will involve.
- What’s the difference between a fuse and a circuit breaker?
Fuses and circuit breakers are both found in the electrical panel (or sub-panel) of a house. They both serve the purpose of cutting the flow of electricity when a circuit gets overloaded—a potentially dangerous situation. Circuit breakers will be found in most houses built after the 1960s or in older buildings that have had their electrical systems upgraded.
Fuses have a thin strip of metal that literally blows when there’s too much electricity flowing through it. When this happens, the fuse needs to be taken out and replaced.
Since the 1960s circuit breakers have been used instead of fuses. They are more convenient, as they just need to be flipped back on if they are tripped. Unlike a fuse, they don’t need to be replaced.
Both circuit breakers and fuses are rated according to how much electricity can flow through them before they trip and shut down the circuit. A 15- or 20-amp fuse is typical for regular light fixtures and such. If the right fuse or circuit breaker isn’t used, it can cause a dangerous situation. Clearly, if a fuse or circuit breaker becomes problematic, an electrician should be called in to look at it.
- Where’s the “main panel?”
This is where all the circuits in the house originate from and it’s usually near where the electric power enters the building. It will be filled with circuit breakers (or fuses in an older building). The main panel has a rating that determines the total amount of current that can flow out to the circuits at one time before the main circuit breaker shuts the entire system down.
Most moderately sized older houses have 100 amp service, though a smaller house might only have 60 amp service. Larger new houses are often built with 200 amp service to accommodate all the electronics used these days. If a buyer is thinking of adding on to a house or just modernizing an older house, one consideration will be if the electrical system is big enough to handle the additional electrical requirements. It’s possible to upgrade the main panel to handle more amps. Again, an electrician can give a buyer an idea of how much work this will be in a particular house.
- Are the outlets grounded?
Nowadays most electrical outlets that you see acknowledge three prong plugs. That is to say, quite often, that the outlet is grounded. An establishing wire, which interfaces with the round third opening, shields against electric current getting away from the circuit and bringing on stuns.
More seasoned houses may just have two prong outlets, which means there’s no establishing security in the circuits. Updating an electrical framework to incorporate establishing wires includes opening the dividers and can be a lot of work. The amount of work it is relies on upon the size, development and design of the house.
GFI outlets (GFI remains for “ground issue interrupter”) are regularly required by construction regulations when introducing an outlet close to a water source or a clammy area. These are the three prong outlets that have two catches on them perusing “test” and “reset.” Since water and metal handles and gushes conduct power, it makes a ground blame especially unsafe in wet areas, for example, a lavatory. A ground deficiency is the place the power wanders off in spite of the establishing wire. In the event that this happens the GFI rapidly cuts the force. GFI outlets are additionally called GFCI, or ground deficiency circuit interrupter.
Overall, knowing how to speak the discussion around a posting’s electrical framework will put a little start in your attempt to make the deal. The essential thing to recall is that at a cost, electrical frameworks can be redesigned and extended to address the issues of the purchaser and also construction regulation prerequisites.
