How Many Of You Noticed The Outrageous Mark-up On Some Parts

I started out helping a friend re-wire a couple outlets in his shop
,and add a few roof exhaust fans
BTW its about 100F PLUS TEMPS!!
(I'm getting a bit too old for this physical abuse)

in the shade in the shop, down here in mid florida,
this time of year if you get up near the rafters:(o_O

now having done this most of my adult life as a side job and never failing any county electrical inspection,
I knew what was required, that and I was employed for 33 years by AT&T as an engineer and lineman.
as with most projects, a few days research into things like local building codes and wire ga vs amp required and loads etc helps a great deal,
it makes ZERO sense to spend time and money doing something, in your shop,
or to buy and install parts and materials,
that can not be assembled to pass local building code inspections

he had to purchase a great many parts to do that, and I noticed the receipt on one box of parts.
now if your dealing in a very small quantity's, the convenience of shopping at the local big box store is usually worth the increased cost.
It became painfully obvious that my friend had no idea how to correctly wire a shop!
he had purchased 14 ga romex to do most of the wiring, and he was adding roof exhaust fans and a 250 amp arc welder outlet:rolleyes::(
I suggested he read the instructions before wiring up an outlet or selecting a breaker
he wanted to use 14 ga wire vs 10 ga, and 8 ga wire, and he had purchased outlets that were no where close to the amp ratings required,
he had not purchased GF! outlets where they were mandated,
he had no idea how to bend, route or cut 3/4" conduit or hook up a ground rod to an electrical breaker box.
after I showed him the ga vs amps charts he conceded the original plan "MIGHT BE FLAWED"
we priced what he needed at lowes and home depot
, conduit,
wire,
outlets,
breakers,
outlet boxes
etc.
yes you need to measure accurately and know,
whats required before you order,
and no most vendors will not take back stuff ordered by mistake,
and found a local electrical contract supply vendor that saved him over $120 in total on those required parts.

You can order virtually anything the electrical supply house has at HD and be able to return any mistakes. Around here special orders can be returned, just have to pay a restocking fee.

A couple months ago I had two exhaust fans installed in our attic. It was a very expensive little project. I did my homework - you can’t skimp on the fan motors as they constantly run and cheap ones don’t last long. I got the best fans for a good price, it was labor that Blew me away. I truly despise having to hire someone for something I used to do myself.
