pushed back to its lowest level since 1969. Wages in blue-collar
industries, such as construction
and maintenance, are rising faster than for white-collar workers.
Pay for people without a college

Gosh, I thought wage growth was stagnant.

There was an article in USA Today yesterday talking about .how wages
are going up across the board and some jobs are really taking off

BTW your link took me to Harbor Fright generators.

About that, why is my 5.5 KW Briggs 11 hp and theirs is 8?
They must have stronger horses in China

In my experience the normal ratio of horsepower to KW is 2:1. Anything
less should be considered suspect.


We shouldn't confuse horsepower and watts with horsepower and generator
output in watts.

1 hp = 745.7 wattsÂ*Â* so 8 hp = 5965.6 watts.Â* That's simply the engine
power.

The generator output in watts will obviously be considerably lower.

Understood but 1 HP = 745.7 watts is the theoretical maximum.Â* In
reality you need considerably more horsepower to produse a KW because
of electrical and mechanical losses, and because the engine is usually
not being run at the RPM which produces peak power.



Agreed.Â* But again, I think the confusion is the conversion of hp to Kw
which is the engine only.Â* It doesn't consider what the engine is doing
with that Kw and the loses occurred in generating an output.

Good example is the current discussion about microwave ovens.Â* There's
some confusion about the rating of the microwave's output power versus
the power required to produce that output.


I happen to have that info handy because I looked it up last week when I
had to replace a dead microwave oven. Here's how it is figured:

A 1200 watt output microwave takes 10. The typical formula for this is..
P = VI.. I = P/V = 1200 /120 =10 A. Hence, one would think that the
answer is 10 A.. However, this formula applies only for DC current. For
AC current,. P=VI cos (theta). where theta is the phase difference
between V and I.. This phase difference is created by the inductances
inside the microwave oven. This phase difference is probably mentioned
on the specifications of the microwave.. Otherwise another specification
maybe mentioned called "MVA".. Power (measured in MVA) = V * I. Using
this , we can directly measure the I.. However, in the absence of either
of the two additional information, it is impossible to fully find I.

The new micro, in the manual, states:

Rated power consumption 1250 watts
Max Microwave output 1200 watts
Frequency 2450 MHz
Rated Current 10.4 A

OF course, those are Chinese measurements.
