## Most critical reviews (10 lowest-rated)

### 1/5 — Clearly not made by an electrician

*2011-01-29, version 1.1*

Terrible, this app can lead to the death of you and your family if you don't already know what you are doing....full of mistakes.

### 1/5 — Lame

*2011-01-01, version 1.1*

One equation on the wheel is even wrong. The sizing doesn't take any de-rating factors into account. Here in Canada anyways, it's not that simple.

### 2/5 — Doesn't reference breaker sizes

*2011-02-17, version 1.1*

Should reference circuit breaker sizes instead of wire ampacities when making selections

### 2/5 — Ok program, electrical

*2010-11-23, version 0*

Needs more info, it's ok

### 3/5 — Important Ground Conductor Distinction

*2012-07-26, version 2.0*

The ground conductor indicated is actually sized to be a Grounding Electrode Conductor for a Service Entrance.  I believe that most folks would prefer, and may be assuming, that it was sized as an Equipment Grounding Conductor.  Beware of this distinction when using this App!

### 3/5 — Close to good

*2011-01-07, version 1.1*

It would be nice if there were options for insulation ratings, conduit types, etc.
I would pay actual money for one that was more comprehensive and as easy to use as this one. For now, this one is easily worth what it cost.

### 3/5 — Needs some more info!

*2010-09-09, version 0*

Being an electrical engineer I do these calcs a bunch and there is great potential here. The insulation thickness needs to be called out and there should be a display of conduit fill in percent to help make a judgement on whether or not to giro the next conduit size. Does this calc take into considerations de rate factor for multiple current carrying conductors?

### 4/5 — Derating

*2012-11-22, version 2.0*

Great app, wish the derating scale had option for F* or C* ambient. Also would be nice to have length of wire run scale.

### 4/5 — Superb App!

*2010-08-11, version 0*

One of the easiest apps I've ever used. I'm thinking of giving all my employees iPhones so they can use this app for wiring design.

### 5/5 — Great

*2012-07-05, version 2.0*

Exactly what I needed!

## Most praised reviews (4 highest-rated)

### 5/5 — Just what I've been looking for

*2012-05-01, version 2.0*

Sizes my wires, does motor calcs. What else do you need?

### 5/5 — Great app

*2010-11-21, version 0*

Fantastic!

### 5/5 — Simple is good

*2010-10-06, version 0*

Nice

### 5/5 — Awesome!!!

*2010-08-21, version 0*

This app is simple and it works! Just get it and you will love it.
