Hello again, one & all,

I speak as an unbiased foreigner who has no experience of FP breakers, of course, but it's interesting to see your comments about the price of replacements as I've just received a (U.S.) hardware catalog which includes electrical equipment.

Single-pole 20A C/B:

Thomas & Betts $2.91
Siemens $3.50
G.E. $4.26
Square D $5.74

Federal Pacific compatible (made by Unique Breakers, Inc.) $16.12

Quite a difference!
