Q2: Do you charge for your estimates?

Q3: I recently bought an air condition unit but it said on the label, 220 volts and all my outlet are 110 volts. What can I do to make it work?

A3: The first thing is to find out whether or not you have 220 volts supply in your 'circuit breaker panel, sometimes referred to as the 'load center'. To find out if you have a 220 volts, you may require to call in an electrician to help you determine or verify the voltage. If it has a 220 voltage then, you may also want to talk with an electrician to install a new power line (outlet/ circuit) from the appropiate panel to the location of your AC unit. If it doesn't have a 220 supply, your second option is to use a 'step-up transformer' rated to meet the load demand/ consumption of the AC unit. However, this is not a common practice in most local and may not be suitable for your situation. Hence, you should consult a qualified electrician or let us know if you need further assistance. The next stept is to, upgrade your meter service based on the recomendation of your electrician. This means you will be required to do some alteration to your existing wiring from the 'service meter' to your 'circuit breaker panel'. If you need more assistance please contact us (4Ds T&D Inc.) by either telephone or email.


Q4: I saw one listing site posting that, your company has no rating by them. Why are they saying that contrary to public record that shown, your company won the "Best Of Brooklyn Award for service of 2017 and 2018 consecutively"? I have known your company for years and I happened to know some of your customers and everyone speak highly of 4Ds T&D Inc. Posted 2017 

A4:  This has been recently drawn to our attention by a few customers and we have seen it ourselves.  We would not name this 'listing site' here but they're not our  affiliate, we do no business with them,  we have never advertised our business with them and have not listed our website with them in-spite their numerous request. See our Home Page for the awards posted.

Our public record and our many satisfied customers are a credible source and recognized form of ratings.  Also, our rating do not depend on any paid advertising agency's favor, period. 


Q5: I have a problem with three of our power outlets and I can't understand why nothing works when I plug them into the outlet. I used my tester screwdriver to check them and all the outlets lit up the tester, showing there is current in the outlets. This is crazy and I don't understand why. Any suggestions?

A5: Tester screwdrivers are best used to give a general idea whether or not current is present in the circuit at that point of testing. However, it cannot determine the absent of an open circuit or the power status. You will need to use a voltage tester/meter to better diagnose a power problem. Based on your description, it seems as though you have an open circuit that feed those affected outlets (faulty or broken line/cable/wire/connection).


Q6: One of the circuit breaker is tripping very often and sometimes it takes a long time before it can be switched back on. What may be the cause?

A6:  There're few things to consider here in order to make the correct diagnosis or determination -: (a) The circuit may be over loaded (b). The breaker is defective. (c) There may be a faulty piece of equipment on that circuit breaker or (d) Faulty or defective wiring may be the cause. These are the most common causes and this will require some diagnostic skills by an 'experience electrical technician' [not all electricians are trained in diagnostic procedures so, if you're not sure who to call, we have the expertise in these and various other forms of electrical diagnostic procedures] to get to the source of the problem and implement corrective measures. 

What is a Motor Starter?

  Motor Starter, Open Box 1 - 4DsElectrical.com

It is an electrical device specially designed to control the high inrush current demands, during the starting sequence (brief moment) of the electrical motor it controls.

An electrical motor at standstill draws a very high current during starting to achieve full speed and the starter protects the motors from any excessive heat built-up during this brief starting moment; due to the high current demand or overload current during regular start operation. The starter can control the start and stop motion of the motor, switch it into forward or reverse, and protect the motor, all at the same time. A Starter primarily consist a combination of components including a Contactor, Overload Protective Heater elements, Start Switch and a Stop Switch in a single unit. Starters are rated by Motor HP (horse power) or Amps (Amperage), indicating how much load capacity and currant it can handle.
