yes . How can I help you ?
somehow I have 3 different eletricain on at the same time
do you have a situation or question I can help you with ?
do you have 3 different questions nopen ???
same question 3 people replied.
there was no querstion here ?
ill close off the other 2. just a sec
I need to know the preferred method used to attach unistrut to cinder block wall. The lengths are 5 ft and I will be mounting at least 3 runs of 1 1/2 emt and at least 6 runs of 3/4 emt
how far apart should the lengths be from each other ??
this is the only pipe or stuff that the unistrut will be supporting
most times with hollow block walls , toggle bolts would be the best method of attachment
are tapcons acceptable ?? not sure that the cells are hallow
just so we are on the same page .. what are you calling tapons .. plastic anchors , lead anchors or metal sleves ??
or metal anchors driven into the block
mettle concrete anchors.
the blue guys . used a lot in Ca
I got that ones that are driven into the wall .. permanent anchors ?
Ohh you mean the ones you screw into the concrete
OK .. if the se are truelly cinder blocks .. then I would be hesitant to use those for supporting these unistrut ... if not installed completely correct the first try they will spin out .. I would favor the use of toggle bolts
reallistically .. the job requires a solid mounting method .. if tappons are what you are comfortable wiuth as a solid mounting method .. then go for it
ok , I thing that 4 per run than ?? how far apart should the struts be from each other ?? I was thinking about 60 inches of so ?
im a little rust y on this .
give me a minute to look up the code
Code says that the conduit neds to be supported at least every 10 feet
and supported at 3 feet or less from a junction box or conduit body
so uni can be 10 feet apart
ok. sounds good. I thatugh that it may have changed. you have been very helpful.
