I need 100 amp 220 3 phase for the yacht I work on to get shore power the dock only has 50 amp 3 phase but there is 2 of the connections Can I combine them and make 100 amp service?

NOT A GOOD IDEA!
Bring in an electrician. It would be well worth the expense and you might be able to find a way to work around those specific requirements.

How to Calculate three phase watts with unbalanced phase current?
You will need to determine the power per phase, and add them up to give the total power of the three-phase load. To do this, you will need to multiply the phase-voltage by the phase current by the power factor -for each phase.

What is phase loss?
Phase loss is the loss of power to a specific area of the circuit. Phase loss can result from exposed wires or damaged wires or even downed power lines.
What is the power factor when the current and voltage are in phase?
The power factor of a load is the cosine of the angle by which the load current lags or leads the supply voltage. So if they are in phase (phase angle is zero), then the power factor must be unity (1).
How does a phase converter work?
A phase converter takes single phase electrical power and turns it into multiphase electrical power. It is very difficult to explain how exactly it does this, but it involves routing power to different capacitors and sequencing them to work together.
How can find out the terminal sequence of a three phase induction motor?
If you are concern about the rotation of the 3 phase motor, all you have to do is connect the power to the three terminal wires, make sure connections are tight, insulate one of the connections properly, the other two just put enough wrap insulation to prevent shortening of the power phases. Bump the motor, that is start it and quickly shut the power of, this way you can check for rotation, if motor is turning in the proper direction, proceed with a thorough insulation of the remaining two connections. If the motor is not turning in the proper direction, switch the connections that were no thoroughly taped, bump motor again it should have changed direction, proceed with taping up the connections.If there is a chance of damaging equipment connected to the motor by bumping it or a panel that has multiply motors connected to it there is a phase sequence meter that can be used to check proper phase sequence. On three phase service rebuilds this meter works great. Get the phasing right at the CDP and all or the motors that are connected to it will be in the right rotation.See related links below
Can you plug a 2 phase welder on a 3 phase plug?
No. Three phase service is something that you would need to request from your power company. You'd need to not only have service, you also need to have an electrician run 3 phase service into your home.
Are food service facilities provided electrical power and potable water after the initial phase is completed?
Negative, during the initial phase
What is a real life application of the square root function?
Electrical engineers use it in calculating power factor and electrical load distribution when dealing with 3 phase power connections.
How can you convert single phase transformer into three phase transformer?
In order to convert from single phase to three phase, you need an inverter or some kind of motor-generator. Variable Frequency Drives for electric motor speed control now feature single phase input with three phase output for motor loads up to 3HP. Good for the home shop where you got a deal on some equipment but lack 3 phase power. For instance, Google this: ATV12H075F1
How can you convert household AC electrical power from single phase to three phase?
For low-power appliances you can buy an electronic power inverter which produces 3-phase outputs from a 1-phase (single phase) service. Such inverters are not cheap to buy so you must decide if it is best to buy an equivalent appliance that runs on 1-phase instead of trying to use a 3-phase appliance on a 1-phase supply using a power inverter. Note: For mains power any 1-phase service is usually obtained by using just one phase of a 3-phase service that comes in overhead or underground cables from the generating station. The power company typically supplies a given neighborhood with a 3-phase service and distributes it as separate 1-phase services, one phase per property or group of properties, so that each property gets a supply of single-phase power. If the owner requires it, it is usually possible to pay the power company to provide a 3-phase service into a house or any other type of property - such as an engineering workshop, vehicle repair garage, etc. - which may need a 3-phase service for machinery or other equipment. +++ An advantage of using an inverter is that many are available with reversing and speed-control, so ideal for driving lathes and similar. Moreover, the machine runs more smoothly: in my own case the noisy resonance of a lathe's welded cabinet stand when running with a single-phase motor stopped entirely when I fitted a 3ph motor and inverter to the same mountings.
What is considered high voltage in a 3 phase system?
There are two aspects to consider: 1. There are several different standard voltages and connections used by the power company in three phase service. 2. Depends if the voltage is measured phase-to-phase or phase-to-ground/neutral. The three phase-to-phase (A-B, B-C, C-A) voltages should be roughly equal. In typical service, they may be 208V or 240V. The phase-to-neutral voltages are sometimes intentionally different. For example, some 3-phase service has a "high leg" that is 208 volts with respect to ground (called a 3 phase high leg delta connection), while the other two legs are 120V with respect to ground, so that you can operate 120V, 240V and 3-phase loads from the same utility service. The important thing is you should always measure before connecting equipment. 208V will fry most 120V electronics.
How can you get 240V single-phase power from a 240V 3-phase service Can you just connect to two poles of the 240V 3-phase service?
If the 240V 3-phase service is 240V phase-to-phase, then you can get 240V single-phase by simply picking two phases (poles, as used in the question) and connecting the load across them. This is simply one third of a standard delta connection. If you need 120V/240V split phase, i.e. with a neutral, as used in residential services, you will need a transformer. If the service is actually a four wire "quadraplex" service, however, you will probably already have that 120V/240V with neutral connection phase available. In this case, you will need to pick the two phases correctly in order to get the proper 120V service half.
What 3 phase cable do you use if the building is 160 meters from the power pole?
This is a voltage drop question. To answer it, a voltage of the service and amperage that the service is going to be have to be stated
How can you get 240V single phase power from a 240V 3 phase service Can you just connect to two poles of the 240V 3 phase service?
I'm sure this isn't what you want to hear, but you probably need to ask an electrician familiar with your service and what you want to connect. As a general answer, you can connect a 240v line to line resistive load like an electric water heater to any 240v source. If you also need the 240v to have 120v line to neutral, like a 240v electric stove that contains a 120v clock and oven light, then its possible if the 3 phase power is connected in a "high delta" configuration, and you connect to the correct leads. If you have a high delta service and want to ignore the 3-phase power service and wire most or all of the loads in the building as a single phase load, the utility may have to be consulted.
How do you wire a two-phase outlet for a stove?
Two-phase power is not generally available anywhere and three-phase is largely used for commercial and industrial applications.Residential power in the United States is single-phase, limited mostly to 240V at the service entrance panel as two legs of 120V each plus a common neutral.If that is what you're making reference to, please see the answers to the Related Questions shown below.
