Planning and Types of Manual Transfer Switches

Experience of power outages in extreme weather makes it necessary for homeowners to explore backup power options. Fortunately, your home can be equipped with built-in backup generator, which is connected to automatic or manual transfer switch.

Planning emergency power strategy

First thing is to determine the appliances you need to run in utility power cuts. In addition, calculate how much power they use. This will allow you to select a generator with ample output capacity.

A 7,500 W portable generator delivers 60 amps and 30 amps at 120V and 240V. It is enough to power few lights and necessary appliances like sump pump, or refrigerator. For powering a central AC or electric range an expensive 15,000W generator is needed.

Generally, a portable generator filled with gasoline has to be installed outdoors, away from doors and windows while it is on. In addition, it will be a bad idea to keep windows or doors open a little for running cords during bad weather.

If you use portable generators to operate appliances usually wired to dedicated circuits directly then it is unsafe. The right way is to connect generator to main load centre with manual changeover switch.

Types of manual transfer switches

Transfer switch kits - Include selected circuit changeover switch, power cord and power inlet.

Selected branch circuits - These transfer switches are designed for fast installation and transfer energy to chosen circuits within the load centre.

Single circuit - This type is economical and ideal for supplying backup power to sump pumps or furnaces or other single circuit applications.

Main or sub transfer panels - Transfer switch and circuit breaker box is combined in these models.

Generator-ready load center - This model blends load centre and transfer switch in s single package.

Whole house/business - This type is perfect for powering the whole house, garage, pole barn or small business.

Industrial and commercial - Single and 3-phase switches up to 600 V are designed especially for industrial, telecom, agricultural, commercial, and municipal applications.

Understand the Difference between Manual and Automatic Transfer Switches

Installing double throw switch is a safe and appealing option that allows you to sit back and relax, while the switch functions on its own.

Two types of transfer switches

• Manual
• Automatic

Manual versus automatic

Manual transfer switch has to be activated by users. After ascertaining that utility outage is a momentary power loss, the homeowner starts the engine manually. The engine has to be allowed to speed up and stabilize. Ultimately, the lever of the transfer switch is thrown into generator position.

The basic transfer device, when total load supplied by regular source (utility or diesel generator) is double pole and double throw switch. Inadvertent connection or back feed of two sources is not possible.

ATS or automatic transfer switch constantly monitors power supplied by the utility company. Grave power quality issues or fluctuations, which may come before an outage triggers a start signal to the generator. As soon as the backup voltage and the frequency become stable, the transfer switch turns the generator.

Once the utility power gets restored and displays no fluctuations for pre-determined time period the switch returns back to its original position. After getting cooled out the generator shuts down automatically. These actions take place without any human intervention.

To switch the manual transfer switch, homeowner will need to go to the entrance panel, even in the dark. Before switching backup power, users need to shut off the breakers for branch circuits that are not essential to decrease the load to match generator capacity. In case the branch circuits are not studied properly, before shutting them, overload to the generator can be caused.

Fortunately, automatic load transfer switch is designed to provide alternating power to those branch circuits that are chosen in advance.

It does not matter, if you use automatic or manual transfer switches. The main feature to consider is the generators capability of supplying necessary connected load.

Common Mistakes to Avoid While Purchasing and Installing Generators

If you desire to avail constant electric supply in commercial or residential spaces then invest in an appropriate quality generator. If you have tight budget then look for used generators. Make sure to pick a reliable supplier for getting the perfect system that suits your budget and needs.

While buying generators many owners make some mistakes and this result in money loss.

Pitfalls to avoid while making a purchase

• Opt for lowest price - Sub-standard electrical appliance can consume more energy, which leads to huge utility bills. In addition, such appliances break down often, which can add to the repair costs.

• Neglecting power needs - Generators differ in providing power capacity. Therefore, it is necessary to understand your power requirements.

Therefore, avoid such mistakes, select branded and genuine generator. Online is the best place to try to find new generators for sales UK. Do a detailed research on different generator brands, models, and specifications to make an informed decision.

After buying a quality standby solution, owners need to realize the hazardous generator mistakes.

Improper placement of generator

Install stationery generator away from home because local codes require it. Portable ones are threat because carbon monoxide released is odorless and invisible. It can be deadly, so keep it away from garages or any windows and doors.

Avoid overusing extension cords

The extension cords may be very old and unsafe to connect it with brand new generator. Install transfer switch with outdoor power inlet. In case of small generators stock new extension cord that can survive 110 V appliances.

Connecting to service panel directly

It is a foolish thought because when power returns, excess backward flow in power line can endanger utility workers.
